There are many types of diodes. According to the semiconductor materials used, they can be divided into germanium diodes (Ge tubes) and silicon diodes (Si tubes). According to its different uses, it can be divided into detection diodes, rectifier diodes, zener diodes, switching diodes, isolation diodes, Schottky diodes, light-emitting diodes, silicon power switching diodes, and rotating diodes. According to the die structure, it can be divided into point contact diodes, surface contact diodes and planar diodes. Point-contact diodes use a very thin metal wire to press the surface of a smooth semiconductor wafer, and a pulse current is passed to sinter one end of the contact wire and the wafer firmly to form a "PN junction". Because it is a point contact, only a small current (not more than tens of milliamps) is allowed to pass, which is suitable for high-frequency low-current circuits, such as radio detection. The surface area of the "PN junction" of a surface-contact diode is large, allowing a large current (several amps to tens of amps) to be passed, and is mainly used in a "rectifying" circuit that converts AC power to DC power. Planar diode is a special silicon diode. It can not only pass a large current, but also has stable and reliable performance. It is mostly used in switches, pulses and high-frequency circuits.

What diode can be used for replacing diode HER308?
The diode HER308 is replaced by HER408 or HER508, which simply means that the specifications are unchanged and the power is increased.
Among electronic components, diode rectifier is a device with two electrodes that only allows current to flow in a single direction. Many uses are made by its rectifying function. The varactor diode (Varicap Diode) is used as an electronic adjustable capacitor. The directivity of the current of most diodes is commonly referred to as the "Rectifying" function. The most common function of a diode is to allow current to flow in only one direction (known as forward bias) and to block in the reverse direction (called reverse bias). Therefore, the diode can be thought of as an electronic version of a check valve.

Can the diode 1N4007 be replaced with 1N5408?
1N4007 reverse voltage 1000V, rectified current 1A;
1N5408 reverse withstand voltage 1000V, rectified current 3A;

From the main parameters, 1N5408 can completely replace 1N4007, but there are some differences in the volume of the two tubes.

1. For rectifier diodes, it is necessary to prevent transient or prolonged overvoltage. Protective devices should be added in combination with actual conditions during use.

2. The model should be selected according to the needs, and the rectifier diodes of the same model can be used in series and parallel. When using in series or parallel, you should decide whether to add equalizing resistors, series voltage equalization, and parallel current sharing according to the actual situation.

3. The temperature has a great influence on the parameters of the diode. When using it, pay attention to good heat dissipation, and if necessary, add a heat sink.

4. It should be noted in practical use that silicon tubes and germanium tubes cannot be replaced. Similar tubes can be replaced. The principle is that the detector tube can be replaced as long as the working frequency is higher than the original tube, and the rectifier tube only needs reverse voltage and forward The current can be replaced if the current is higher than the original tube.

Schottky diode, also known as Schottky barrier diode (SBD for short), is a low-power, ultra-high-speed semiconductor device.

The most significant feature is the extremely short reverse recovery time (which can be as small as a few nanoseconds), and the forward voltage drop is only about 0.4V. It is mostly used as high-frequency, low-voltage, high-current rectifier diodes, free-wheeling diodes, protection diodes, and also used as rectifier diodes and small-signal detection diodes in circuits such as microwave communications. It is more common in communication power supplies and inverters.

A typical application is in the switching circuit of a bipolar transistor BJT, which is clamped by connecting a Shockley diode to the BJT, so that the transistor is actually close to the off state in the on state, thereby increasing the switching speed of the transistor. This method is a technique used in the TTL internal circuits of typical digital ICs such as 74LS, 74ALS, 74AS.

The biggest feature of Schottky diodes is that the forward voltage drop VF is relatively small. At the same current, its forward voltage drop is much smaller. In addition, its recovery time is short. It also has some disadvantages: the withstand voltage is relatively low, and the leakage current is slightly larger. Take full consideration when choosing.

SPS 0.5W 75V Switching Diodes 1N4148 DO 35 Package
datasheet: http://www.spsdiode.com/Datasheet/SPS-1N4148.pdf 

1N4148 is a small high-speed switching diode, which is fast in switching. It is widely used in circuits with higher signal frequencies for unidirectional isolation, communication, computer boards, television circuits and industrial control circuits.

A very common high-frequency switching diode. Including DO35, LL34, SOD323, SOT23, 0805 packages.
75V reverse withstand voltage and 150mA average forward current, very suitable for general rectification.
4pF junction capacitance and 4nS reverse recovery time are sufficient for most applications.
A small-signal high-frequency diode that is very easy to obtain, and inexpensive and versatile.

Difference between 1N4148 and 1N5819:
High frequency, low voltage, and high current characteristics are the differences between 1N5819 diodes and ordinary diodes. It is widely used in switching power supplies, inverters, drivers and other circuits for high frequency, low voltage, high current rectification, freewheeling, and protection diodes.
1N5819 is characterized by extremely fast speed (low switching loss), extremely low forward voltage drop (low voltage loss), but low reverse withstand voltage, usually less than 60V, suitable for low voltage (not higher than 12V) switching power supply.
Another use of the 1N5819 diode is voltage regulation, which takes advantage of its reverse characteristics. Therefore, when the withstand voltage is low and the current is not large, you can consider using a voltage regulator instead.
1N4148 is a point-contact, small-current, high-frequency switching diode with high speed, but the operating current is only 150mA. It is widely used in circuits with higher signal frequencies.
The reverse leakage current of the 1N5819 tube is a bit larger, but the capacitance is small and the speed is fast. But it is not as fast as 1N4148, after all, the purpose of 1N4148 is high-frequency detection, not rectification.

Difference between 1N4148 and 1N4007:
1N4148 and 1N4007 can be replaced with each other in emergency in general low current (below 100mA, reverse voltage below 100V), and unimportant occasions,
1N4148 is a small current switch tube, 100V withstand voltage,
1N4007 is a rectifier tube, 1A-1000V. There are many types of substitute models.

SPS 5A 20V 100V SKY SMD Diodes SS52 SS54 SS56 SS58 SS510 SMC Package

Max.Average Forward Rectified Current: 5.0A

What is the SS510 diode? Can it be used in the output diode of switching power supply?
SS510 is a Schottky diode in a chip package, rated at 5A / 100V;
Generally used as the output diode of the switching power supply.
Pay attention to the rated voltage and current when using, and pay attention to derating.

Which diode can replace SS310?
SS315, SS320, SS510 models can replace SS310.

SS310 belongs to Schottky diode. Schottky diode is named after its inventor Dr. Schottky. SBD is short for Schottky Barrier Diode (abbreviated as SBD).

SBDs are not made using the principle of forming a PN junction between a P-type semiconductor and an N-type semiconductor, but are made using the metal-semiconductor junction principle formed by the metal-semiconductor contact. Therefore, SBD is also called metal-semiconductor (contact) diode or surface barrier diode, it is a kind of hot carrier diode.

Schottky diodes have a low forward voltage drop and fast switching speeds. Compared with traditional diodes, the only disadvantage is that their reverse voltage is very low, and their reverse leakage current can reach a relatively high value, but this has little effect on the circuit.
