The 53 V reverse standoff voltage means it stays out of the circuit under normal conditions, then breaks down at 58.9 V min and hard-clamps at 85 V max while shunting 17.6 A of peak pulse current (10/1000 µs waveform). That 85 V ceiling is what the downstream silicon sees — if the protected part's abs-max rating is below that, this diode won't save it. ## Obsolete — sourcing through independent channels Vishay lists the 1.5KE62AHE3/51 as obsolete. A board-level repair technician who sees a scorch mark on this part in an automotive ECU will need to source it as a one-off replacement, not a production-run buy. ## Package and mounting for the rework bench Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE body sits in a 0.040-inch diameter hole on a standard 0.100-inch pitch. The axial leads are tin-plated copper — the rework tech can clip the old part out and solder the replacement without hot air, but the large anode tab on the cathode side sinks heat fast; a 350°C iron with a chisel tip and a dab of flux on the pad clears the joint cleanly.","metaTitle":"Vishay 1.5KE62AHE3/51 TVS Diode, 1.5kW, 85V Clamp, DO-201AA","metaDescription":"Obsolete Vishay 1.5KE62AHE3/51 TransZorb automotive TVS, 1.5kW peak pulse, 53V standoff, 85V clamp.
