That 1500 W rating is the energy-handling ceiling for a single transient; if your line sees repetitive surges, derate per the pulse derating curve in the datasheet. The reverse standoff voltage is 376 V, meaning the diode stays high-impedance below that level and only starts conducting when the transient exceeds the 418 V minimum breakdown. ## Automotive qualification and temperature envelope The 175°C Tj max gives headroom above the 150°C typical automotive limit, useful for high-ambient locations near exhaust or turbocharger paths. It handles the thermal cycling of automotive environments without the solder-joint fatigue risk of surface-mount packages under vibration.","metaTitle":"1.5KE440CAHA0G TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE440CAHA0G bidirectional Zener TVS, 1500W peak pulse, 376V standoff, AEC-Q101 automotive grade.
