Breakdown voltage is specified at a minimum of 285V, meaning the device begins clamping when the transient exceeds this level, and the clamping voltage is held to 414V maximum at the rated 5A peak pulse current, limiting the voltage stress on downstream components. ## Obsolete — sourcing through independent channels Available through independent surplus and excess inventory channels; each reel is lot-traceable and sourced from franchised or authorized distributor overstock. Quantities are confirmed at RFQ — no standing stock is held.","metaTitle":"Microsemi 1.5KE300CAE3/TR13 TVS, 1500W, 256V Standoff","metaDescription":"Microsemi 1.5KE300CAE3/TR13 bidirectional Zener TVS, 1500W peak pulse, 256V standoff, DO-201AA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Microsemi Corporation","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Obsolete","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"CASE-1","Voltage - Breakdown (Min)":"285V","Voltage - Clamping (Max) @ Ipp":"414V","Voltage - Reverse Standoff (Typ)":"256V","Current - Peak Pulse (10/1000µs)":"5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE300CAE3%2FTR13/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microsemi-corporation/1.5KE300CAE3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microsemi-corporation/1.5KE300CAE3-TR13 when reusing this data.
