Because the part carries AEC-Q101 qualification, any replacement candidate should also hold automotive-grade certification to avoid re-qualification cost. The DO-201AA axial footprint is common across the 1.5KE series, so a parametric substitute with the same standoff and clamping voltages may fit the same board hole pattern. ## Package and mounting note Through-hole DO-201AA (DO-27) axial package — the body is 9.1 mm long with 0.96 mm diameter leads. The tape-and-box (TB) packaging option is intended for hand-insertion or low-volume assembly; for automated lines, verify the reel/ammo pack variant. Operating junction temperature range is -55°C to +175°C, covering the full automotive under-hood and cabin thermal envelope. No power-line protection feature — this is a pure transient suppressor, not a continuous overvoltage clamp.","metaTitle":"1.5KE10HE3/73 Vishay TVS, 1.5kW, 8.1V Standoff, Obsolete","metaDescription":"Vishay 1.5KE10HE3/73 TransZorb TVS, 1500W peak pulse, 8.1V standoff, 15V clamp.
