The reverse standoff voltage is 64.1V, meaning the TVS draws negligible leakage below this DC level and only activates when the transient exceeds the minimum breakdown voltage of 71.3V. This guard band between standoff and breakdown ensures the diode stays off during normal 48V or 60V bus operation but triggers before the downstream silicon sees damaging overvoltage. ## Through-hole axial package and temperature range for industrial assembly Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE75A-/73 is a through-hole part suited for wave solder or hand-solder assembly on boards where surface-mount TVS pads might crack under mechanical stress. The axial body allows point-to-point wiring or insertion into a PCB with formed leads. The wide temperature range means the breakdown voltage and clamping characteristics shift predictably across temperature, but the 1500W rating is derated above 25°C per the manufacturer's power derating curve.","metaTitle":"1.5KE75A-E3/73 Vishay TransZorb TVS, 1500W, 104V Clamp","metaDescription":"Vishay 1.5KE75A-E3/73 TransZorb TVS diode, 1500W peak pulse power, 104V clamping, unidirectional, DO-201AA axial.
