The freewheeling diode, also known as a suppressor diode, catch diode, snubber diode, or flyback diode, is used to eliminate a sudden voltage spike across an inductive load when its supply voltage is abruptly removed or reduced. From: Gallium Oxide, 2019 ...
A novel free wheeling diode with its blocking capability of 1700 V is presented to realize an excellent trade-off characteristic between a forward voltage drop and a reverse recovery loss, for the first time. A superior forward voltage drop (Vf) of 1.85 V with the reverse recovery loss (Err...
A freewheeling diode, CAL-HD, with a new minority carrier lifetime control is presented. The diode exhibits lower forward voltage drop and higher rated current as compared to the exisiting CAL diode. Additionally, a positive temperature coefficient near to the nominal current has been achieved. ...

forward current and low junction temperature, it is likely that all fast power diodes produce excessive voltage spikes due to snappy recovery [1]. This in turn can destroy the diode and ultimately cause a circuit failure due to excessive ...
1. Freewheeling diode reverse-recovery failure during IGBT turn-on.One of the most common and catastrophic failure modes infast diodes is due to diode snappy recovery. Previous work hasshown that, under adverse combinations of high commutating, large circuit stray inductance, low forward current,...
Design of the Freewheeling Diode In the below diagram a freewheeling diode is placed across the inductor. An ideal flyback diode will have a very large peak forward current; capacity which helps in handling the voltage transients from burning out the diode,inductor’s power supplyis suited for...
