Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limitsare exceeded, device functional operation is not implied, damage may occur and reliability may be affected.
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, tw 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.
