The bidirectional construction means it clamps both positive and negative transients, so no polarity worry when protecting AC-coupled or floating lines. ## AEC-Q101 qualification and the operating envelope An engine control unit or transmission sensor module that sees 125 °C ambient still has margin before the TVS derates. The supplier device package is listed as DO-214AB (SMCJ), meaning the same copper leadframe and solder pad layout as the SMCJ series — no board spin needed if you are migrating from a different 1500 W TVS in the same case.","metaTitle":"1.5SMC30CAHE3/9AT TVS Diode, 1500W, 25.6V, DO-214AB","metaDescription":"Vishay 1.5SMC30CAHE3/9AT bidirectional TVS, 1500W peak pulse, 25.6V standoff, AEC-Q101 qualified.
