1500 W bidirectional transient suppressor
The 1.5SMC220CA-M3/9AT: Its 1500 W peak pulse power rating (10/1000 µs waveform) means it absorbs a single high-energy surge — a 24 V industrial bus or a 48 V telecom feed hit by a lightning-induced transient — without failing short. Clamping is specified at 328 V maximum at the 4.6 A peak pulse current — the voltage the load sees during the event stays below that ceiling.
Package and thermal envelope
The single bidirectional channel replaces two back-to-back unidirectional TVS diodes in a single component — saves board area and reduces the parts count on the rail.
