When a surge exceeds the 285 V minimum breakdown threshold, the device clamps at 414 V maximum to shunt the energy away from the downstream circuit. The DO-201AA axial-lead through-hole package is the legacy footprint for this power class — the same body used across the 1.5KE series. ## Lifecycle reality for the BOM line Vishay lists the 1.5KE300CA-/73 as Obsolete in its lifecycle record. No official successor order code is provided by the manufacturer.","metaTitle":"1.5KE300CA-E3/73 Vishay TVS, 1500W, 256V Standoff, DO-201AA","metaDescription":"Vishay 1.5KE300CA-E3/73 TransZorb® TVS, 1500W peak pulse, 256V reverse standoff, bidirectional.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Vishay General Semiconductor - Diodes Division","Type":"Zener","Series":"TransZorb®","Package":"Tape & Box (TB)","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":"1.5KE300","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Voltage - Breakdown (Min)":"285V","Voltage - Clamping (Max) @ Ipp":"414V","Voltage - Reverse Standoff (Typ)":"256V","Current - Peak Pulse (10/1000µs)":"3.6A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE300CA-E3%2F73/alternatives.json"},"ai":{"faq":[{"question":"Is the 1.5KE300CA-/73 unidirectional or bidirectional?","answer":"It is a single-channel bidirectional device, meaning it clamps both positive and negative surges symmetrically — suited for AC signal lines or bipolar DC rails."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE300CA-E3-73","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE300CA-E3-73 when reusing this data.
