ORDERING INFORMATION
(1) VDRM and VRRM for all types can be applied on a continuous basis. Ratings
apply for zero or negative gate voltage; however, positive gate voltage shall
not be applied concurrent with negative potential on the anode. Blocking
voltages shall not be tested with a constant current source such that the
voltage ratings of the devices are exceeded.
(2) Ratings apply for tw = 1 ms. See Figure 1 for ITM capability for various
duration of an exponentially decaying current waveform, t w is defined as
5 time constants of an exponentially decaying current pulse.
(3) Test Conditions: IG = 150 mA, VD = Rated VDRM, ITM = Rated Value,
TJ = 125°C.
