ABSOLUTE MAXIMUM RATINGS(1,5)
DRAIN Voltage .................................. .............-0.3 V to 700 V
Peak DRAIN Current: LNK362................200 mA (375 mA)(2)
LNK363/364.........400 mA (750 mA)(2)
FEEDBACK Voltage ...........................................-0.3 V to 9 V
FEEDBACK Current ...................................................100 mA
BYPASS 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.
