The DO-201AA axial-lead package (also known as DO-27) requires a 1.1 mm diameter hole per lead on a 2.54 mm pitch — standard for through-hole TVS insertion alongside terminal blocks or screw connectors. Supplier device code 1.5KE matches the standard Vishay TransZorb® footprint; no custom pad geometry is needed for the 1500 W power dissipation — the lead frame and body handle the surge energy without additional heatsinking. No stock-holding claim — quoted to order per RFQ.","metaTitle":"Vishay 1.5KE33A-E3/73 TVS Diode, 1.5kW, 28.2V Standoff","metaDescription":"Vishay 1.5KE33A-E3/73 TransZorb® TVS, 1500W peak pulse, 28.2V reverse standoff, 45.7V clamp.
