That 59.3 V clamp ceiling means downstream components rated for 60 V or higher survive the surge without secondary protection. ## Automotive qualification and deployment context This part carries AEC-Q101 qualification, the automotive-grade stress and reliability standard for discrete semiconductors. The TransZorb series is Vishay's branded TVS platform, optimized for fast response to transients in automotive and telecom applications.","metaTitle":"1.5SMC43CAHM3_A/H TVS Diode, 1500W, Bidirectional, DO-214AB","metaDescription":"Vishay 1.5SMC43CAHM3_A/H bidirectional TVS, 1500W peak pulse, 36.8V standoff, AEC-Q101 qualified.
