For shorter transients (e.g. 8/20 µs from ESD or lightning), the peak current capability is higher, but the clamp voltage remains at 246 V maximum. Breakdown occurs at a minimum of 171 V (the Zener knee), so a rail regulated at 154 V stays below the avalanche threshold in normal operation. The unidirectional channel means this is a single-direction clamp — reverse-polarity protection requires a second device or a series blocking diode. Operating temperature spans -65°C to 150°C junction — sufficient for outdoor telecom cabinets or industrial enclosures where ambient heat and self-heating from repetitive surges stack. ## DO-214AB footprint and board integration No power line protection feature is listed — this is a general-purpose TVS for DC rails and signal lines, not an AC mains surge protector.","metaTitle":"Vishay 1.5SMC180A-M3/57T TVS Diode, 154V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC180A-M3/57T Zener TVS diode, 1.5 kW peak pulse, 154V reverse standoff, 246V clamping.
