Reverse standoff sits at 7.78 V typ, establishing the continuous working voltage the TVS presents to the protected rail in normal operation; the 8.65 V minimum breakdown voltage guarantees the device stays in its high-impedance state below that threshold. ## AEC-Q101 qualification and thermal margin AEC-Q101 automotive qualification means the part passed the discrete semiconductor stress sequence: humidity, temperature cycling, mechanical shock, and vibration — relevant for telecom outdoor equipment as well, since the qualification set overlaps with industrial environmental demands.","metaTitle":"Vishay 1.5SMC9.1CAHM3/H TVS Diode, 1.5 kW, 7.78 V","metaDescription":"Vishay 1.5SMC9.1CAHM3/H, AEC-Q101 automotive TVS diode, 1.5 kW peak pulse, 13.4 V clamping at 112 A.
