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.

SPS 3A 50V-1000V Axial Diodes 1N5400 1N5401 1N5402 1N5404 1N5406 1N5407 1N5408 DO-27 Package

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.
