The 28.5V minimum breakdown voltage ensures the device stays out of conduction during normal 24V system ripple, while the 41.4V clamp keeps the protected node below typical downstream component abs-max ratings for 40V-tolerant parts. ## Automotive qualification and temperature range AEC-Q101 qualification means this part has passed automotive-grade reliability stress tests including high-temperature reverse bias, temperature cycling, and ESD immunity per the automotive electronics council standard. Target applications include automotive electronic control units, telecom line cards, and general-purpose transient suppression where 1500W peak pulse capability is needed in a surface-mount DO-214AB footprint. ## DO-214AB package and reflow considerations The tape-and-reel packaging (TR) suits high-volume pick-and-place assembly. No power line protection feature is built in — this is a unidirectional TVS for signal or low-side power rail clamping, not for AC mains. The single-channel unidirectional design protects one rail per device.","metaTitle":"Vishay 1.5SMC30AHM3_A/H TVS Diode, 25.6V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC30AHM3_A/H automotive TVS diode, 1500W peak pulse, 25.6V reverse standoff, AEC-Q101 qualified.
