That means it carries documented reliability data for temperature cycling, ESD, and latch-up immunity that an OEM auditor will expect in a PPAP submission. For a 24 V automotive bus protected by this diode, the clamping margin to downstream components is well-defined. ## Electrical ratings and thermal envelope These figures define the protection corridor for a 185 V continuous rail — the diode stays transparent below standoff and conducts only on overvoltage events. The product status is Active per the manufacturer's lifecycle record. No end-of-life notice or last-time-buy window is on file.","metaTitle":"1.5SMC220AHM3_A/H TVS Diode, 1.5kW, 185V, AEC-Q101","metaDescription":"Vishay 1.5SMC220AHM3_A/H TVS Zener diode, 1500W peak pulse, 185V standoff, AEC-Q101 qualified for automotive.
