Notes:
1. All voltages referenced to SOURCE, TA = 25 °C.
2. Duration not to exceed 2 ms.
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 specified 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.
6. -1 V for current pulse ≤5 mA out of the pin and a duration
of ≤500 ns.
7. Normally limited by internal circuitry.
