1.5kW pulse rating, AEC-Q101 qualified
The 1.5SMC110AH is a 1500W (1.5kW) peak pulse power TVS diode from Taiwan Semiconductor, part of the 1.5SMC series. It is a Zener-type device with a single unidirectional channel. The 94V reverse standoff voltage (Vrwm) and 105V minimum breakdown voltage place it in the 100V-class protection tier, clamping at 152V maximum at the 10.3A peak pulse current (10/1000µs waveform).
Package and board-fit
Housed in a DO-214AB (SMC) surface-mount package, the 1.5SMC110AH mounts directly to the PCB. The package footprint is standard for the SMC family, and the Tape & Reel packaging supports automated pick-and-place assembly. The part is not intended for power line protection — the specification explicitly marks Power Line Protection as 'No', meaning it is designed for signal or DC rail clamping, not AC mains.
