Relationship between diode forward recovery effect and devices

What is the relationship between diode forward recovery effect and devices?

We will not discuss the cause of the diode forward recovery phenomenon here, but we can think that it is an inherent property of semiconductor devices. In most cases, the positive recovery effect does not cause any problems, so it is rarely discussed. As for this effect, there are several characteristics to be noted:

1. The higher the diode temperature, the stronger the positive recovery effect, and the longer the amplitude and time;

2. The higher the voltage and current, the stronger the forward recovery effect;

3. Different brands of devices and devices of different brands may have different degrees of positive recovery effect, even if they are of the same voltage or current grade or voltage or current grade;
