The standoff of 7.78 V gives the bus legitimate headroom at normal operating conditions, and the 8.65 V minimum breakdown is the threshold where the device starts conducting during a transient event. ## AEC-Q101 qualification for under-hood deployment The automotive and telecom applications in the series designation are not marketing language; they refer to the test stress profile and theabus test conditions the part has passed. Single unidirectional channel — this is the correct topology for protecting a positive-supply rail from transient overvoltage. It does not conduct in the reverse direction during normal operation, so the 7.78 V standoff sits below the rail it is guarding. ## Surface-mount assembly and sourcing posture Surface-mount DO-214AB SMC in Tape & Reel — the industry-standard footprint for this power class, compatible with standard hot-air and IR reflow profiles. The Tape & Reel format supports high-volume automated placement without manual kitting.","metaTitle":"Vishay 1.5SMC9.1AHM3_A/I TVS Diode, 1500W peak, 112A","metaDescription":"Vishay 1.5SMC9.1AHM3_A/I automotive TVS diode, 1500W peak pulse, 13.4V clamping, 112A surge, AEC-Q101, DO-214AB SMC surface mount.
