Product details

The 1.5SMC30C: Single bidirectional channel — one device protects both polarities, simplifying layout on AC or bipolar DC lines where the signal swings through zero.

No power line protection — this is a signal- or low-power-rail TVS, not designed for mains or high-energy transient suppression on power distribution.

For a BOM sustaining an existing design, the 1.5SMC30C can be sourced to order. No pin-compatible drop-in replacement from Littelfuse is documented; a parametric search on 25.6 V standoff, 1500 W, bidirectional, DO-214AB will surface functional equivalents from other brands for a board-spin evaluation.

Frequently asked questions

What is the closest pin-compatible alternative to the 1.5SMC30C?

A functional replacement requires a parametric search: bidirectional TVS, 25.6 V standoff, 1500 W peak pulse, DO-214AB package. Several manufacturers offer parts meeting these parameters, but a board-spin may be needed to confirm fit.
