At the 6.5A peak pulse current the clamping voltage hits 230V max, which is the voltage the protected circuit must survive. Breakdown occurs at 144V min, giving a 14V guard band between the standoff and the avalanche threshold. Unidirectional single-channel design — the cathode band marks the anode for PCB orientation. ## DO-201AA axial package — board-fit note Through-hole DO-201AA (DO-27) axial body. The lead diameter and body length match the standard 0.100-inch pitch hole grid — no footprint change needed if replacing another 1.5KE-series part in the same hole pattern. Operating junction temperature range is -55°C to 175°C, so the diode handles the self-heating from repetitive surges in a sealed enclosure without derating the peak power below 1500W. ## Sourcing reality for an obsolete TransZorb Stock moves through surplus and broker channels only. No official successor order code is published by Vishay for this specific variant. If a production BOM needs a drop-in, the 1.5KE series shares the same DO-201AA footprint and pinout across voltage grades — a parametric search at the same 130V standoff and 1500W rating turns up active alternatives from the same family.","metaTitle":"1.5KE160-E3/73 Vishay TransZorb TVS, 1500W, 130V","metaDescription":"Vishay 1.5KE160-E3/73 Zener TVS diode, 1500W peak pulse, 130V reverse standoff, DO-201AA axial.
