Product details

1500 W bidirectional clamp for 43.6 V rails

The 1.5SMC51CA-M3/9AT: Its 1500 W peak pulse power rating (10/1000 µs waveform) handles surge events from inductive kickback, lightning-induced transients, or ESD strikes in industrial and telecom equipment.

Clamping voltage and breakdown margin

The single bidirectional channel means one device protects a signal pair or a floating supply rail without needing two unidirectional parts back-to-back.

DO-214AB (SMC) surface-mount footprint

The supplier device package designation is DO-214AB (SMCJ). Supplied on Tape & Reel, it is compatible with high-volume pick-and-place assembly.

Sourced to order against BOM quantities; availability and pricing confirmed at quote time through independent distribution channels.
