The 1500 W rating means the device can absorb a single 10/1000 µs surge up to that power level without exceeding the junction temperature limit of 175 °C. For repetitive transients, the average power dissipation must be derated per the datasheet thermal impedance curve. ## Package and board integration Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE75CA-/73 mounts through-hole. The leaded form factor suits point-to-point wiring, terminal blocks, or PCB through-holes in power-supply and industrial-control boards where surface-mount TVS diodes are not preferred due to board thickness or thermal cycling requirements. The wide junction temperature margin ensures the clamping performance holds across the full ambient range without derating the surge capability.","metaTitle":"Vishay 1.5KE75CA-E3/73 TransZorb TVS, 1500W Bidirectional","metaDescription":"Vishay 1.5KE75CA-E3/73 TransZorb bidirectional TVS diode, 1500W peak pulse power, 64.1V standoff, 104V clamp.
