The 112A peak pulse current is the complementary axis: it tells you how much surge current the diode can conduct without failing, given a source impedance low enough to drive 112A into the 13.4V clamping level. On a 12V automotive rail the clamping headroom — 13.4V max vs the 7.78V standoff — means the downstream bus sees a 5.6V overvoltage spike during the event before the TVS turns on, so downstream inputs must tolerate that transient width. The -55°C to +175°C junction temperature range puts this squarely in the automotive thermal band — the 175°C upper limit accommodates engine-bay mounting where board-level ambient can hit 125°C in still-air enclosures. Derate the peak pulse power at elevated Tj to stay within the datasheet derating curve. ## AEC-Q101 TransZorb® — automotive qualification on a TVS TransZorb® is Vishay's trademark for their bidirectional TVS architecture built on Zener punch-through — the unidirectional channel means it clamps positive transients on a single-polarity rail, not a bidirectional clamp. The AEC-Q101 qualification commits the part to automotive temperature grade, lifecycle screening, and PPAP documentation — the rating matters most for safety-critical and under-hood power nodes where a field failure is not an option. The 7.78V reverse standoff sets the continuous working voltage below which the TVS remains off in normal operation; the 8.65V minimum breakdown is where it begins conducting. ## DO-201AA axial — through-hole mounting and board thermal path The DO-201AA (DO-27) axial leaded package mounts in a board hole and is wave-soldered or hand-soldered — the lead length acts as a thermal shunt, pulling heat away from the junction during surge events. For peak pulse operation, ensure the lead-to-pad solder fillet is complete; a dry joint here raises the thermal resistance and reduces effective surge capability. Bulk pack is the standard format for through-hole TVS reels; tape-and-reel is not listed.","metaTitle":"Vishay 1N6270AHE3/51 TVS Diode, 1500W Peak Pulse","metaDescription":"Vishay 1N6270AHE3/51 unidirectional Zener TVS, 1500W peak pulse, 112A peak pulse current, AEC-Q101 qualified.","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":"Automotive, AEC-Q101, TransZorb®","Package":"Bulk","Applications":"Automotive","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":"1N6270","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"8.65V","Voltage - Clamping (Max) @ Ipp":"13.4V","Voltage - Reverse Standoff (Typ)":"7.78V","Current - Peak Pulse (10/1000µs)":"112A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5346","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/55e3e40e24fd2c3f96443c3e231bf459.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1N6270AHE3%2F51/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the 1N6270AHE3/51 and how do I get a price?","answer":"No live stock position is held on the shelf."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1N6270AHE3-51","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/1N6270AHE3-51 when reusing this data.
