The 459V reverse standoff voltage means the part stays transparent on a nominal 400V bus (telecom or industrial DC rail) and only conducts when the line exceeds 513V breakdown. This window suits overvoltage protection on 3-phase rectified supplies or PoE+ injectors where the steady-state rail sits at 350–450V. ## Automotive temperature range and package The DO-201AE axial-lead package (through-hole) allows manual or wave-solder assembly and provides a low-inductance path for fast transients. ## Active production and sourcing posture Micro Commercial Co lists the 1.5KE540CA-TP as active in production.","metaTitle":"Micro Commercial Co 1.5KE540CA-TP TVS Diode, 1500W","metaDescription":"1.5KE540CA-TP TVS diode, 1500W peak pulse, 459V standoff, 740V clamping, bidirectional, DO-201AE, active production, sourced to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Micro Commercial Co","Type":"Zener","Grade":"Automotive","Series":"-","Package":"Bulk","Applications":"Telecom","Mounting Type":"Through Hole","Package / Case":"DO-201AE, Axial","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE540","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201AE","Voltage - Breakdown (Min)":"513V","Voltage - Clamping (Max) @ Ipp":"740V","Voltage - Reverse Standoff (Typ)":"459V","Current - Peak Pulse (10/1000µs)":"2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5272","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9600442db46e1e617905b120f9f9b3c6.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/micro-commercial-co/1.5KE540CA-TP","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/micro-commercial-co/1.5KE540CA-TP when reusing this data.
