For a new design, look at the active 1.5KE series variants from Vishay or a pin-compatible TVS from a second source in the same DO-201AA package — the 66.4V standoff and 1500W rating are common enough that a parametric cross is straightforward.","metaTitle":"1.5KE82CHE3/73 TVS Diode, 1500W, 66.4V Standoff","metaDescription":"Vishay 1.5KE82CHE3/73 automotive AEC-Q101 TransZorb TVS, 1500W peak pulse, 66.4V standoff, 118V clamp, DO-201AA axial.
