The 15.3V reverse standoff voltage (working voltage) means it sits across a 12V or 15V rail without conducting leakage — it only clamps when the transient exceeds the 17.1V minimum breakdown threshold. At the 60A peak pulse current (10/1000µs waveform), the clamping voltage is held to 25.5V max. For a 12V rail powering sensitive logic, that clamp margin is tight but within the abs-max of most 5V and 3.3V downstream regulators when the TVS is placed close to the board entry. ## Package and board-fit The 1.5KE series uses a standard 0.042-inch diameter lead — it fits existing DO-201 footprints without a layout change. Operating junction temperature range spans -55°C to 175°C — the 175°C ceiling gives margin for high-ambient enclosures or crowded boards where the TVS self-heats during repetitive surge events.","metaTitle":"1.5KE18CA R0G TVS Diode, 1.5kW, 15.3V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE18CA R0G bidirectional Zener TVS, 1500W peak pulse, 15.3V standoff, 25.5V clamp, 60A Ipp. Active, through-hole DO-201AA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Taiwan Semiconductor Corporation","Type":"Zener","Series":"1.5KE","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE18","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"17.1V","Voltage - Clamping (Max) @ Ipp":"25.5V","Voltage - Reverse Standoff (Typ)":"15.3V","Current - Peak Pulse (10/1000µs)":"60A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a688563676897fea683fa9d5a5542f4e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE18CA%20R0G/alternatives.json"},"ai":{"faq":[{"question":"What package does the 1.5KE18CA R0G come in?","answer":"Through-hole axial DO-201AA (DO-27), also referenced as DO-201 supplier device package.
