The 246V clamping ceiling is the number to check against the downstream component's absolute maximum rating — if the protected IC can survive 250V for the pulse duration, this diode keeps it safe. ## Through-hole package swaps in the field Housed in a DO-201AA (DO-27, Axial) through-hole package with a DO-201 supplier device package designation, this diode is a hand-tool swap — no hot-air station needed. The axial leads are polarity-marked on the body; the bidirectional channel means orientation doesn't matter, which cuts the risk of a reverse-install mistake on a service call. ## Active production, no end-of-life watch needed General-purpose application class means it fits power-supply input protection, DC bus clamping, and signal-line transient suppression without a dedicated automotive or telecom qualification — though the wide temperature range covers most industrial environments.","metaTitle":"YAGEO 1.5KE180CA/B TVS Diode, 154V Standoff, 1500W Peak","metaDescription":"YAGEO 1.5KE180CA/B bidirectional TVS diode, 154V reverse standoff, 171V breakdown, 246V clamping, 1500W peak pulse power.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"YAGEO","Type":"Zener","Series":"1.5KE","Package":"Box","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"171V","Voltage - Clamping (Max) @ Ipp":"246V","Voltage - Reverse Standoff (Typ)":"154V","Current - Peak Pulse (10/1000µs)":"6.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1035","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4b2937e75354924aacfedfdea02966d9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE180CA%2FB/alternatives.json"},"ai":{"faq":[{"question":"Can I replace a 1.5KE180CA with 1.5KE180CA/B?","answer":"The /B suffix indicates a bidirectional channel — one device protects both polarities.
