The -55°C to 150°C junction temperature range covers under-hood and engine-bay thermal profiles with margin. ## Clamping and breakdown parametrics for BOM fit Minimum breakdown voltage is 17.1 V, so the diode starts conducting at that threshold. Maximum clamping voltage at the rated 60 A peak pulse current is 25.5 V. This is the voltage the downstream circuitry must survive during a transient event. For a 24 V-tolerant ECU input, the 25.5 V clamp provides a 0.5 V guard band; for a 12 V-rated IC, an additional series resistor or secondary clamp is needed. The single bidirectional channel protects one signal or power line against both positive and negative transients in a single package — no need for two unidirectional diodes back-to-back. ## Package, mounting, and production status Housed in the DO-214AB (SMC) surface-mount package, the same footprint as standard SMC diodes. The tape-and-reel packaging suits automated pick-and-place assembly. The base product number is 1.5SMC18, with the 'C' indicating bidirectional and 'A' indicating 5% tolerance on breakdown voltage.","metaTitle":"1.5SMC18CAHR7G TVS Diode, 1500W, Bidirectional, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC18CAHR7G automotive TVS diode, 1500W peak pulse, 15.3V standoff, AEC-Q101 qualified.
