Absolute Maximum Ratings(1,4)
DRAIN Voltage ...................................................-0.3 V to 72ꢀ V Notes:
DRAIN Peak Current: TNY284......................... 400 (7ꢀ0) mA(2) 1. All voltages referenced to SOURCE, TA = 2ꢀ °C.
TNY28ꢀ....................... ꢀ60 (10ꢀ0) mA(2) 2. The higher peak DRAIN current is allowed while the DRAIN
TNY286....................... 720 (13ꢀ0) mA(2)
voltage is simultaneously less than 400 V.
TNY287....................... 880 (16ꢀ0) mA(2) 3. Normally limited by internal circuitry.
TNY288..................... 1040 (19ꢀ0) mA(2) 4. 1/16 in. from case for ꢀ seconds.
TNY289..................... 1200 (22ꢀ0) mA(2) ꢀ. Maximum ratings specified may be applied one at a time,
TNY290..................... 1360 (2ꢀꢀ0) mA(2)
EN/UV Voltage ...................................................... -0.3 V to 9 V
EN/UV Current .............................................................. 100 mA
