The 4.6 A peak pulse current at that waveform means the device can handle a 4.6 A surge for 1 ms without exceeding the junction temperature limit. For shorter transients (e.g. 8/20 µs), the peak current capability is significantly higher, roughly scaling by the square root of the pulse width ratio. The clamping voltage of 328 V at 4.6 A is the voltage the load sees during the surge — a downstream component with a 350 V absolute maximum rating has 22 V of margin. If the load's abs-max is below 328 V, a lower-clamping TVS or a multi-stage protection scheme is needed. ## Package and board integration The axial leads suit point-to-point wiring, terminal block termination, or PCB through-hole mounting with a 0.100-inch lead spacing. The package body is epoxy molded, and the leads are solderable per standard wave or hand-soldering profiles.","metaTitle":"Vishay 1.5KE220CA-E3/73 TransZorb TVS, 1500W, 185V Standoff","metaDescription":"Vishay 1.5KE220CA-E3/73 bidirectional TVS diode, 1500W peak pulse, 185V reverse standoff, DO-201AA axial.
