Product details

TVS clamp for 154V rails

The 1.5SMC180A-M3/9AT: It clamps transients on a 154V nominal rail — the reverse standoff voltage (154V) is the continuous DC bias it blocks; when a surge exceeds the 171V breakdown threshold, it conducts and clamps at 246V max, shunting up to 6.1A of peak pulse current (10/1000µs waveform) away from the protected load.

DO-214AB (SMCJ) footprint — standard for TVS diodes in this power class. No power line protection function (the device is a standalone clamp, not a filter). Operating temperature range -65°C to 150°C junction, covering industrial and outdoor enclosure environments.
