1500 W peak pulse in a DO-201 axial body
The 1.5KE62A-HF: That 85 V clamp ceiling is the figure a downstream regulator or IC input must survive without failing — the TVS absorbs the energy and holds the voltage below the device's abs-max rating.

Comchip Technology 1.5KE-HF series Zener TVS diode, 1.5KE62A-HF, 1500W peak pulse power, 85V clamping, unidirectional, DO-201AA axial, through hole.
