The 1.5 kW peak pulse rating at 10/1000 µs defines its survivable transient energy window — it clamps fast rise-time voltage spikes on a line before those spikes reach downstream circuitry. General-purpose classification means it is not a dedicated power-line protector; it is sized for signal and rail protection in industrial, communications, and instrumentation equipment. ## Clamping performance — standoff, breakdown, and peak pulse current Reverse standoff of 13.6 V is the maximum working voltage at which the device stays off in normal operation — the line can sit at this level indefinitely without the TVS drawing significant leakage. ## Temperature grade and what the 175°C junction ceiling allows The -55°C to 175°C junction temperature range places this part in the high-reliability and industrial temperature band. The upper bound is the junction limit under thermal shutdown — the part self-protects by limiting conduction if the transient energy budget is exceeded repeatedly, but the 175°C ceiling means it tolerates significant thermal headroom above typical commercial ambient ratings. In a poorly ventilated enclosure with a sustained clamping event, the diode will absorb the 1500 W pulse for the defined 10/1000 µs window, and the steady-state derating follows the standard derating curve for the DO-201AA package. The 1N6276A-/51 carries a Last Buy lifecycle designation — Vishay General Semiconductor has moved this part toward end-of-life and the official procurement window is closing. A board-level redesign is the long-term path if production quantities are needed beyond the remaining channel stock; the TransZorb® series family may carry pin-compatible alternatives in the same DO-201AA footprint, but any substitution should be verified against the clamping and peak pulse specs on the target schematic.","metaTitle":"1N6276A-E3/51 TVS Diode, 1.5 kW Peak Pulse, DO-201AA","metaDescription":"Vishay 1N6276A-E3/51 unidirectional Zener/TVS diode, 13.6 V standoff, 15.2 V breakdown, 22.5 V clamping, 66.7 A peak pulse, DO-201AA axial.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Vishay General Semiconductor - Diodes Division","Type":"Zener","Series":"TransZorb®","Package":"Bulk","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Last Time Buy","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1N6276","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"15.2V","Voltage - Clamping (Max) @ Ipp":"22.5V","Voltage - Reverse Standoff (Typ)":"13.6V","Current - Peak Pulse (10/1000µs)":"66.7A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7268","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1N6276A-E3%2F51/alternatives.json"},"ai":{"faq":[{"question":"What does the 22.5 V clamping voltage mean for protecting a 24 V rail?","answer":"A 24 V nominal rail sees transients that can spike well above 24 V — the standoff of 13.6 V is below 24 V, so this part is not a direct clamp on a 24 V nominal supply rail. It is better suited to protecting rails, sense lines, or control circuits in the 12 V to 15 V working range where the 15.2 V breakdown and 22.5 V clamp ceiling sit below the absolute-maximum rating of the protected circuitry."},{"question":"Is there a pin-compatible replacement in the same TransZorb® series?","answer":"The TransZorb® family spans a wide voltage and power range in the DO-201AA package, but the specific 1N6276A base part number is the anchor — any alternative must match the 13.6 V standoff, 15.2 V breakdown, 22.5 V clamping, and 66.7 A peak pulse rating. No official cross-reference or second-source order code is listed for this exact part, so substitution requires confirming the clamping characteristic against the protected load rather than relying on a family cross-reference alone."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1N6276A-E3-51","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/1N6276A-E3-51 when reusing this data.
