Notes:

1. All voltages referenced to SOURCE, T

A = 25 °C

2. Maximum ratings specified may be applied one at a time without

causing permanent damage to the product. Exposure to Absolute

Maximum Ratings conditions for extended periods of time may

affect product reliability.

3. Self-supply not active.

4. Normally limited by internal circuitry.

5. 1/16” from case for 5 seconds.

6. Non-repetitive pulse.

7. Voltage of D1 pin relative to D2 pin in either polarity.

8. The peak current is allowed while the D1/D2 voltage is simultane-

ously less than 400 V.
