Product details

Clamping window and surge rating

The 1.5SMC51A M6G: The 1500 W peak pulse power rating (1.5 kW) defines the energy-handling capability for a single 10/1000 µs pulse. For a given rail voltage, this determines whether the TVS can absorb the expected surge without exceeding the junction temperature limit of 150°C.

The package footprint is shared across the 1.5SMC series, so a single PCB land pattern serves multiple voltage variants. Supplied in Tape & Reel packaging, it is ready for automated pick-and-place assembly.

Lifecycle and sourcing posture

The part carries no power-line protection rating — it is designed for transient suppression, not continuous overvoltage clamping.
