Product details

1500 W peak pulse — AEC-Q101 TransZorb for 185 V rails

The 1.5SMC220AHE3/9AT is a 1500 W peak pulse power Zener TVS diode from Vishay's 1.5SMC series, built on the TransZorb technology. The unidirectional single-channel design protects one DC rail per device.

The 1500 W rating in a standard JEDEC outline means the board layout is shared across the 1.5SMC family — the same copper pad and thermal via pattern works for any voltage variant in the series. Supplied on Tape & Reel (TR), the 1.5SMC220AHE3/9AT is ready for automated pick-and-place. Store the reels dry — the DO-214AB body is not moisture-sensitive by default, but the reel label carries the MSL level if one is assigned.

Frequently asked questions

What is the closest pin-compatible alternative to the 1.5SMC220AHE3/9AT in this TVS family?

Any unidirectional 1500 W TVS in the DO-214AB package from the same 1.5SMC series shares the same footprint and solder pad. The voltage variant must match the protected rail — the 1.5SMC220AHE3/9AT is set for 185 V standoff; a different voltage code (e.g., 1.5SMC200A for 171 V standoff) changes the clamping threshold but not the board layout.
