That 79 V window between standoff and clamp gives the downstream circuitry a defined protection threshold — a 200 V-rated MOSFET or a 250 V-rated capacitor sees a hard ceiling before its own breakdown. No power line protection feature is built in; this is a standalone transient suppressor, not a filtered or coordinated protector. ## Thermal and mechanical fit The DO-201AA (DO-27) axial-lead through-hole package is the standard footprint for 1.5 kW-class TVS diodes. Junction temperature range spans -55°C to 175°C, covering industrial enclosures and under-hood automotive compartments without derating at the hot end. The axial leads solder into a plated through-hole board; the body stands off the PCB, so convection cooling around the epoxy case is the primary heat path during a pulse.","metaTitle":"1.5KE150CA R0G TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE150CA R0G bidirectional Zener TVS diode, 1500W peak pulse power, 128V standoff, 207V clamp, DO-201 axial.","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":"1.5KE150","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"143V","Voltage - Clamping (Max) @ Ipp":"207V","Voltage - Reverse Standoff (Typ)":"128V","Current - Peak Pulse (10/1000µs)":"7.6A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2712","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a688563676897fea683fa9d5a5542f4e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE150CA%20R0G/alternatives.json"},"ai":{"faq":[{"question":"What package does the 1.5KE150CA R0G come in?","answer":"It is supplied in a DO-201AA (also known as DO-27) axial-lead through-hole package, on tape and reel."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5KE150CA-R0G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/taiwan-semiconductor-corporation/1.5KE150CA-R0G when reusing this data.
