PIN diodes have "poor" reverse recovery time. But what is its order? Any guesses? I know it is a few microseconds for a PN diode. Correct me if I am wrong!
Madam, I had already gone through Wikipedia and found nothing on the reverse recovery time part. Wiki says, PIN diodes have "poor reverse recovery time". I guess milliseconds. Can someone correct me, please.
Have you checked this out: https://www.youtube.com/watch?v=G5rVLQQx0OU
The link you have provided is for a PN diode madam!
I think I have finally found it on youtube: https://www.youtube.com/watch?v=3QdWDstDPuE
It is in microseconds for a PIN diode and nanoseconds for a PN diode. Correct me if I am wrong!
The reverse recovery time of either the pn diode and the pin diode depends on the minority carrier life time and it is about 7 Tau, with the Tau the minority carrier lifetime. In case of fast recovery diodes the minority carrier lifetime is made very small by adjusting the lifetime by gold doping or electron irradiation. This is called lifetime killing in power devices to reduce their recovery time in order to operate them at higher switching speeds.
To get an idea how large the reverse recovery diode could be please refer to the link: http://www.farnell.com/datasheets/315151.pdf
