Product details

1.5kW unidirectional TVS in DO-214AB — key clamp ratings

The Vishay 1.5SMC47A-M3/57T is a 1500W peak-pulse-power Zener TVS diode from the 1.5SMC series, designed for general-purpose overvoltage protection. It is a unidirectional device with a single protection channel.

Package, mounting, and temperature range

Supplied in Tape & Reel (TR) packaging, it is ready for automated pick-and-place assembly.

Lifecycle and sourcing posture

No official second-source cross-reference is recorded, but the standard DO-214AB footprint means parametric equivalents from other TVS families can be evaluated for dual-sourcing.

Frequently asked questions

What package and mounting does 1.5SMC47A-M3/57T use?

It uses a DO-214AB (SMC) surface-mount package, also referred to as SMCJ. It is supplied in Tape & Reel packaging for automated assembly and has an operating temperature range of -65°C to +150°C.
