The breakdown voltage range starts at 14.3 V minimum, ensuring the avalanche region is entered before the downstream IC's abs-max rating is exceeded. The junction temperature range spans -65 °C to +150 °C, covering the full automotive under-hood and passenger-compartment thermal profile. The AEC-Q101 qualification includes the full suite of stress tests — temperature cycling, high-temperature reverse bias, and ESD robustness — required for tier-one ECU programs. No power line protection is integrated; the device is a standalone transient suppressor for signal and low-power supply rails.","metaTitle":"Vishay 1.5SMC15CAHM3/H TVS Diode, 1500W, Bidirectional","metaDescription":"Vishay 1.5SMC15CAHM3/H bidirectional TVS diode, 1500W peak pulse power, AEC-Q101 qualified, 12.8V standoff, DO-214AB.
