For a 300 V nominal rail, the 333 V breakdown provides margin before the TVS begins conducting leakage current. ## AEC-Q101 qualified, -65 to 150 °C junction range Part of the Automotive, AEC-Q101, 1.5SMC, TransZorb® series. AEC-Q101 qualification means it meets the automotive-grade stress and reliability tests for discrete semiconductors — temperature cycling, high-temperature reverse bias, and ESD robustness. ## DO-214AB (SMC) surface-mount package Surface-mount assembly with tape-and-reel packaging for automated pick-and-place. The package is rated for the full 1500 W peak pulse without derating at 25 °C ambient. No power line protection — this is a unidirectional Zener TVS for DC rail clamping, not AC line surge suppression.","metaTitle":"1.5SMC350AHE3_A/I Vishay TVS, 1500W, 300V Standoff, DO-214AB","metaDescription":"Obsolete Vishay 1.5SMC350AHE3_A/I Zener TVS diode, 1500W peak pulse, 300V reverse standoff, AEC-Q101 qualified.
