DRAIN Pin Voltage ...................................-0.3 V to 725 V (677x) Notes:
DRAIN Pin Voltage ..........................-0.3 V to 650 V (666x/676x) 1. Peak DRAIN current is allowed while the DRAIN voltage is
(1)
DRAIN Pin Peak Current: …………………….......... 1.6 x ILIMIT(TYP)
simultaneously less than 400 V.
BYPASS Pin Voltage .............................................-0.3 V to 9 V 2. -1 V for current pulses ≤5 mA out of the pin and a duration
BYPASS Pin Current .................................................... 100 mA of ≤500 ns.
FEEDBACK Pin Voltage .......................................-0.3 V to 9 V(2) 3. Maximum ratings specified may be applied one at a time
