Webb4 feb. 2016 · The reverse recovery time is still 200ns as expected. The small Trr makes this diode suitable for high current switchmode use, but even so, one of the limits to the …
Webb4 feb. 2016 · The reverse recovery time is still 200ns as expected. The small Trr makes this diode suitable for high current switchmode use, but even so, one of the limits to the operating frequency is how fast the diodes come out of conduction. Synchronously driven FETs instead of diodes can overcome this limitation. Finally we look at the unknown diode.
WebbThis diode with a p-n junction is designed to make the reverse recovery time (trr) smaller and is also called a high-speed diode. Compared to general rectifying diodes, the trr is 2 to 3 digits smaller because the FRD is designed with a switching power supply to rectify high frequencies of tens of kHz or hundreds of kHz.
