Its 66.4 V reverse standoff and 118 V clamping at 12.7 A (10/1000 µs pulse) make it a fit for 48 V and 60 V bus clamping in engine-control and body-electronics modules. ## What the key ratings mean for your BOM Bidirectional single-channel topology — the same device clamps both polarities, so a single part covers reverse-battery and load-dump events without external bridge diodes. Breakdown voltage min 73.8 V ensures the avalanche threshold sits above the 66.4 V standoff, giving margin against steady-state rail ripple. The DO-201AA axial package (1.5KE supplier device code) is a through-hole leaded form that handles the thermal cycling of engine-bay solder joints better than a surface-mount DO-214AB in the same duty. ## Lifecycle reality — obsolete, sourced through surplus channels Vishay lists the 1.5KE82CHE3/54 as obsolete.","metaTitle":"Vishay 1.5KE82CHE3/54 TVS Diode, 1.5kW, DO-201AA","metaDescription":"Obsolete Vishay 1.5KE82CHE3/54 Zener TVS diode, 1500W peak pulse, 66.4V standoff, AEC-Q101, DO-201AA axial.
