DEFINITIONS
VF
= Instantaneous forward voltage (pw = 300
μs, D = 2%).
IR
= Instantaneous reverse current.
Trr
= Reverse recovery time (See Figure 9), summation of ta
+ tb.
ta
= Time to reach peak reverse current (See Figure 9).
tb
= Time from peak IRM
to projected zero crossing of IRM
based on a straight line from peak IRM
through 25% of IRM
(See Figure 9).
Qrr
= Reverse recovery charge.
CJ
= Junction Capacitance.
RθJC
= Thermal resistance junction to case.
pw = pulse width.
D = duty cycle.
