When a surge hits, the device clamps at 18.2V maximum while conducting 82.4A peak pulse current — the downstream IC sees no more than 18.2V, which is within the abs-max rating of most 12V-rated automotive ECUs and telecom line cards. ## Automotive-grade temperature range and qualification The operating junction temperature range spans -65°C to 150°C, covering under-hood ambient conditions where the diode may sit near an engine block or exhaust manifold. The TransZorb® construction delivers low leakage at high temperature — a key parameter when the TVS shares a PCB with a hot power stage. ## DO-214AB SMC package and board integration The DO-214AB (SMC) package is a standard surface-mount footprint for 1.5kW-class TVS diodes. The copper tab on the bottom side conducts heat to the PCB pad; a 1 oz copper pour of at least 30 mm² under the tab keeps the junction temperature within the 150°C limit during repetitive surges. Tape & Reel packaging feeds directly into pick-and-place lines — the reel quantity is the unit for inventory planning, not individual pieces. ## Bidirectional channel saves a diode on bipolar lines On an RS-485 bus or a CAN transceiver's differential pair, one 1.5SMC13CAHM3_A/I replaces two unidirectional TVS diodes in anti-series — reducing component count and PCB area. The 11.1V standoff also matches the common-mode voltage range of 12V automotive CAN interfaces.","metaTitle":"1.5SMC13CAHM3_A/I Vishay TVS, 1.5kW, 11.1V Standoff","metaDescription":"Vishay 1.5SMC13CAHM3_A/I bidirectional TVS diode, 1500W peak pulse, 11.1V reverse standoff, 18.2V clamp.
