The 1500W rating means it absorbs a single 1ms surge without failing; for repetitive events, the power derates linearly above 25°C. Through-hole DO-201AA (DO-27) body with axial leads — the lead spacing is non-standard, so the hole pattern on the PCB must match the actual lead spread of the part in hand. The -/73 suffix denotes Tape & Box packaging, which is the standard Vishay bulk format for axial diodes; the same die is also available in tape-and-reel (-/54) or ammo-pack (-/1) if the pick-and-place feeder requires a different carrier. Power line protection is marked as 'No' — this part is designed for signal and low-power DC bus clamping, not for direct AC mains or high-energy power-line surge suppression where a higher energy MOV or gas tube would be specified. ## Lifecycle and supply posture Listed as Active by Vishay — the 1.5KE series is a long-running TransZorb family with no announced end-of-life.","metaTitle":"1.5KE18CA-E3/73 Vishay TVS, 1.5kW, 15.3V Standoff","metaDescription":"Vishay 1.5KE18CA-E3/73 TransZorb TVS, 1500W peak pulse, 15.3V reverse standoff, bidirectional, DO-201AA.
