5 V/div ( = 1 A/div), 20 ns/div.
20%-80% switching time shown.
S/N 11713. 5m cable used.
The above waveform shows the transition from a forward current of +0A to a reverse
current of -4A, approximately. The reverse transient is nearly unchanged, relative to the
case when the forward current was +2A! The CSD10120 datasheet says "this is a
majority carrier diode, so there is no reverse recovery charge", and the results above
largely support this.
UTG8042 RESULTS
The Microsemi UTG8042 is a dual ultrafast rectifier in a TO-3 package. With the
amplitudes set to +100V and -200V, the following reverse recovery waveform is
obtained at the test jig "OUT" terminal:
