Breakdown starts at 20.9 V minimum, and the clamping voltage peaks at 30.6 V at the rated 51 A peak pulse current — that clamp keeps downstream silicon inside its abs-max rating. ## Package and board-fit for surface-mount assembly The SMC footprint is larger than the smaller SMA/SMB siblings — the extra copper area helps spread the transient heat into the board, which matters when the 1.5 kW pulse raises the junction temperature in microseconds.","metaTitle":"1.5SMC22A V7G TVS Diode, 1500W, 18.8V Standoff, DO-214AB","metaDescription":"1.5SMC22A V7G Zener TVS from Taiwan Semiconductor, 1500W peak pulse, 18.8V reverse standoff, 30.6V clamp.
