The 12.8 V reverse standoff voltage sits just above a nominal 12 V supply, so the diode stays out of the circuit during normal operation and only conducts when the line spikes above its breakdown threshold (14.3 V min). ## Surface-mount DO-214AB and temperature range Housed in the DO-214AB (SMC) package, it is a standard surface-mount footprint for TVS diodes — the same pad layout as the SMCJ series, so it drops into existing board layouts without a footprint change.","metaTitle":"Vishay 1.5SMC15A-M3/9AT TVS, 1500W, 12.8V, DO-214AB","metaDescription":"Active Vishay 1.5SMC15A-M3/9AT Zener TVS diode, 1500W peak pulse, 12.8V reverse standoff, DO-214AB SMC.
