The 8.65 V minimum breakdown is where conduction definitively starts under the test condition. ## Automotive temperature grade and AEC-Q101 qualification Rated junction temperature spans -65 to +150 °C — the upper bound covers engine-bay and transmission-adjacent deployments where local ambient can reach 125 °C and the junction still holds margin. AEC-Q101 qualification means the part passed humidity, temperature cycling, and surge-life stress testing to the automotive electronics reliability standard — the series carries both automotive and telecom application flags, so the thermal cycling and peak pulse endurance are characterised for field environments beyond a benign-office rating. ## Package, mounting, and sourcing posture The DO-214AB (SMC) package is the mid-size TVS footprint — the cathode tab carries the heat from the clamping event, so the land pattern and solder joint quality on the tab directly affect the thermal impedance the device sees during a real transient. Tape-and-reel packaging is standard for high-volume SMT assembly.","metaTitle":"Vishay 1.5SMC9.1CAHM3_A/I TVS Diode, 1500W, 7.78V standoff","metaDescription":"Vishay 1.5SMC9.1CAHM3_A/I unidirectional TVS Zener, 1.5 kW peak pulse, 7.78 V standoff, 13.4 V clamping, AEC-Q101, DO-214AB SMC.
