If your BOM still calls for the 1.5KE220-/54, the DO-201AA axial footprint is common across the 1.5KE family, so a pin-compatible functional equivalent from the same series may substitute with a parametric check. ## DO-201AA axial — board-fit and thermal note Through-hole DO-201AA (DO-27) axial package — the leads are tin-plated copper and the body is molded epoxy. The junction operates from -55°C to 175°C, so the part handles the self-heating from a 1500 W pulse without derating at room ambient. For repetitive surges, the lead length and PCB copper area under the body set the thermal impedance; keep the leads as short as the assembly process allows to minimize inductance between the TVS and the protected rail.","metaTitle":"Vishay 1.5KE220-E3/54 TVS Diode, 1.5kW, 175V Standoff","metaDescription":"Vishay 1.5KE220-E3/54 TransZorb® TVS, 1500W peak pulse, 175V standoff, 344V clamp.
