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.

What is the difference between HER207 and RL207? Is it interchangeable?

The main difference is the conduction recovery time of the two. HER207 works at tens of kHz, while RL207 can only work below 1 kHz.
According to the principle of large replace small, high replace low, HER207 can replace RL207, and vice versa.

RL207 is 1000V / 2A ordinary rectifier diode, HER207 is 1000V / 2A high efficiency fast recovery diode. Based on the specific use of the diode in the circuit, then consider if use RL207 replace HER207, it is better not to rashly replace.
