The -65°C to +150°C junction temperature range covers cold-crank starts and under-hood heat soak — the leakage current at 150°C is higher than at 25°C, but the clamping voltage stays within the datasheet limits across the full band.","metaTitle":"1.5SMC15CAHM3_A/H Vishay TVS, 1500W, 12.8V, DO-214AB","metaDescription":"Vishay 1.5SMC15CAHM3_A/H bidirectional TVS diode, 1500W peak pulse, 12.8V standoff, AEC-Q101, DO-214AB.
