ABSOLUTE MAXIMUM RATINGS(1,5)
DRAIN Voltage ................................................-0.3 V to 700 V
DRAIN Peak Current: TNY274.......................400 (750) mA(2)
TNY275.....................560 (1050) mA(2)
TNY276.....................720 (1350) mA(2)
TNY277.....................880 (1650) mA(2)
TNY278...................1040 (1950) mA(2)
TNY279 ................. 1200 (2250) mA(2)
TNY280 ................. 1360 (2550) mA(2)
EN/UV Voltage ................................................... -0.3 V to 9 V
EN/UV Current ........................................................... 100 mA
BP/M Voltage ......................................................-0.3 V to 9 V
Storage Temperature ......................................-65 °C to 150 °C
Operating Junction Temperature(3) .................-40 °C to 150 °C
Lead Temperature(4) .......................................................260 °C
Notes:
1. All voltages referenced to SOURCE, T
A = 25 °C.
2. The higher peak DRAIN current is allowed while the
DRAIN voltage is simultaneously less than 400 V.
3. Normally limited by internal circuitry.
4. 1/16 in. from case for 5 seconds.
5. Maximum ratings specified may be applied one at a time,
without causing permanent damage to the product.
Exposure to Absolute Maximum Rating conditions for
extended periods of time may affect product reliability.
