No power line protection rating (: No) means this TVS is intended for signal or low-side DC rail clamping, not for mains AC or high-energy surge suppression where a dedicated MOV or gas tube would be specified. ## Sourcing and compliance posture The base product number 1.5KE56 covers the voltage family; the 'CA' suffix marks the bidirectional polarity, 'A0G' the tape-and-box packaging.","metaTitle":"1.5KE56CA A0G TVS Diode, 1500W, 77V Clamp, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE56CA A0G bidirectional Zener TVS diode, 1500W peak pulse power, 77V clamp at 20A, DO-201 axial package.","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 & Box (TB)","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)","Base Product Number":"1.5KE56","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"53.2V","Voltage - Clamping (Max) @ Ipp":"77V","Voltage - Reverse Standoff (Typ)":"47.8V","Current - Peak Pulse (10/1000µs)":"20A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7008","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/80774f0a0eec8384469a0373c58968b1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE56CA%20A0G/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5KE56CA-A0G","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/1.5KE56CA-A0G when reusing this data.
