The 14.6 A peak pulse current rating at that pulse width is the figure to size the upstream impedance against; a shorter, higher-di/dt surge will produce a higher clamping let-through before the device settles. ## AEC-Q101 qualification for under-hood and telecom deployments AEC-Q101 is the automotive discrete semiconductor stress qualification — it validates the part for temperature cycling, humidity, surge life, and electrical overstress at the grades required for engine-compartment and cabin-domain circuits. Telecom applications add a different stress profile — the 64.1 V standoff sits between the common 48 V telecom bus rail and the protected rail, so the part is positioned for primary-side protection on 48 V-rated equipment where a surge on the line must not propagate to downstream electronics.","metaTitle":"Vishay 1.5SMC75AHM3_A/I Zener TVS, 1.5kW, 64.1V standoff","metaDescription":"Vishay 1.5SMC75AHM3_A/I, automotive AEC-Q101 Zener TVS in DO-214AB SMC. 1.5kW peak pulse, 64.1V standoff, 104V clamping.
