The reverse standoff voltage is 50.2 V, so the diode stays high-impedance below that threshold and only conducts when the transient exceeds the 55.8 V minimum breakdown. This gives a clean protection window for a nominal 48 V supply line. ## Package and deployment context Housed in a DO-201AA (DO-27) axial-lead through-hole package, the device is intended for board-level soldering — common in PSU output stages, telecom line cards, and industrial control boards where a leaded part survives thermal cycling better than a surface-mount equivalent.","metaTitle":"Vishay 1.5KE62-E3/54 TransZorb TVS, 1500W, 50.2V Standoff","metaDescription":"Vishay 1.5KE62-E3/54 Zener TVS diode, 1500W peak pulse, 50.2V reverse standoff, 89V clamping.
