It clamps voltage spikes on a single power rail, protecting downstream circuitry from transients that exceed the standoff rating. With a 53V reverse standoff typ and a clamping maximum of 85V at 17.6A peak pulse (10/1000 µs waveform), the device sits above the nominal rail so it stays passive during normal operation and avalanche-clamp only during a transient event. ## How the clamping specs drive protection design For longer-duration transients the clamping voltage rises, so the 85V ceiling applies only at the rated 17.6A peak current. Budget the system clamping voltage above 85V if the source impedance allows a higher let-through current. The 58.9V minimum breakdown voltage sets the threshold where the TVS begins to conduct — it sits comfortably above the 53V standoff typ, giving roughly 11% of headroom before the device turns on. That margin is deliberate: it prevents false triggering from rail noise while keeping the clamp point predictable. AEC-Q101 qualification means it has passed the temperature cycling, humidity, and electrical stress screens required for engine-compartment and body-electronics deployments. ## Sourcing the part Listed Active by the manufacturer. No official successor is cited on the lifecycle record.","metaTitle":"Vishay 1.5SMC62AHE3/9AT TVS Diode, 53V standoff","metaDescription":"Vishay 1.5SMC62AHE3/9AT unidirectional Zener TVS diode, AEC-Q101 qualified, 53V standoff / 85V clamping, DO-214AB (SMC).
