That 1500 W rating means it absorbs a short, high-energy surge — like a load-dump or inductive kickback — without failing short, and the 15.6 V clamp protects downstream 12 V rails from overshoot. The reverse standoff voltage is 9.4 V, so it sits across a 12 V nominal bus and stays transparent until a transient exceeds that threshold. Breakdown starts at 10.5 V minimum, giving a narrow window before the clamp engages fully. This part carries AEC-Q101 automotive qualification — the same stress and reliability screening used for under-hood and cabin electronics. The operating junction temperature range is -65 °C to 150 °C, covering cold-crank and under-hood heat soak. It is a unidirectional device with one channel, so it protects a single rail against positive transients; for AC or bidirectional protection you would need two back-to-back or a bidirectional variant. The DO-214AB (SMC) package is a standard surface-mount footprint for TVS diodes in this power class. The large copper tab on the bottom side conducts heat into the PCB pad — the 1500 W rating assumes a low-thermal-resistance board layout with adequate copper area under the package.","metaTitle":"Vishay 1.5SMC11AHE3/57T TVS, 1500W, 15.6V Clamp, DO-214AB","metaDescription":"Vishay 1.5SMC11AHE3/57T Zener TVS diode, 1500W peak pulse, 15.6V clamping, AEC-Q101 automotive grade.
