The breakdown voltage range starts at 456 V minimum, which means the diode begins conducting before the clamp voltage is reached — the avalanche region absorbs the surge energy before the downstream silicon sees overstress. The 2.28 A peak pulse current at the clamp voltage shows the diode's ability to sink substantial surge current without failing short. ## DO-201AA axial through-hole — mounting and board fit Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE480A-/54 mounts through-hole on the PCB. The axial body allows point-to-point wiring or socketed insertion in high-reliability designs where surface-mount reflow might stress the junction. ## Active production — sourcing posture Vishay lists the 1.5KE480A-/54 as Active.","metaTitle":"Vishay 1.5KE480A-E3/54 TVS Diode, 1.5kW, 408V Standoff","metaDescription":"Vishay 1.5KE480A-E3/54 TransZorb® TVS, 1500W peak pulse, 408V reverse standoff, 658V clamp.
