The -65°C to 150°C junction temperature range covers under-hood ambient plus self-heating at peak pulse; the wide thermal envelope suits both engine-bay and outdoor telecom enclosures.","metaTitle":"1.5SMC18CAHM3_A/H Vishay TVS, 1500W, 15.3V Standoff","metaDescription":"Vishay 1.5SMC18CAHM3_A/H bidirectional TVS, 1500W peak pulse, 15.3V standoff, AEC-Q101.
