Notes:
1. All voltages referenced to SOURCE, T
A = 25 °C.
2. Duration not to exceed 2 msec.
3. 1/16 in. from case for 5 seconds.
4. The higher peak DRAIN current is allowed while the DRAIN
voltage is simultaneously less than 400 V.
5. Maximum ratings specied may be applied, one at a time
without causing permanent damage to the product.
Exposure to Absolute Maximum ratings for extended
periods of time may affect product reliability.
