The 25.5 V maximum clamping voltage at 60 A Ipp gives a 10.2 V margin above the 15.3 V standoff — adequate for most 15 V bus transients without secondary breakdown. Power line protection is not supported — this is a unidirectional device for DC rails, not AC mains. ## Through-hole DO-201 package Supplied in a DO-201AA (DO-27) axial leaded package, through-hole mount. The DO-201 footprint is standard for 1.5 kW TVS diodes — the large body and axial leads handle the thermal pulse without board-level heat sinking. Bulk packaging suits low-to-medium volume assembly. ## Active production, no direct cross Taiwan Semiconductor lists the 1.5KE18A B0G as Active. For BOM continuity, the 1.5KE series is widely second-sourced by other brands — confirm pin-compatible alternatives at RFQ.","metaTitle":"1.5KE18A B0G TVS Diode, 1500W, 15.3V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE18A B0G Zener TVS, 1500W peak pulse, 15.3V reverse standoff, 60A Ipp. Active production.
