Product details

The Littelfuse 1.5SMC47AT3G is a Zener-type transient voltage suppression (TVS) diode from the 1.5SMC series, designed to clamp overvoltage transients on power and signal lines in general-purpose circuit protection applications.

Package, mounting, and environmental ratings

No power line protection is claimed — this part is intended for signal or low-power rail clamping, not for direct AC mains suppression.

For sustainment programs or last-time-buy requirements, this part is sourced through independent distribution channels against an RFQ.

Frequently asked questions
