The 1.5SMC160AHM3/H is a 1500 W peak-pulse-power Zener TVS diode from Vishay's 1.5SMC series, qualified to AEC-Q101 for automotive use. It is a unidirectional device (single channel) in a standard DO-214AB (SMC) surface-mount package. The 1500 W rating means it can absorb a single 1 ms surge up to that power level without failing — sizing the TVS to the expected transient energy, not just the steady-state line voltage.
Automotive-grade qualification and operating envelope
The operating junction temperature range spans -65 °C to 150 °C, covering under-hood and exterior-mounted electronics.
The part ships on tape and reel, compatible with automated pick-and-place. No special moisture-sensitivity-level (MSL) bake is required beyond the standard JEDEC profile for this package class.
