The 1.5 kW peak pulse rating (10/1000 µs waveform) is the headline figure: it tells you the device survives a single 1.5 kW transient without degradation, and the 143 A peak pulse current confirms it can handle the current magnitude that a real surge injects into the circuit. ## Three voltage specs, one selection decision The reverse standoff voltage of 5.8 V is the working rail the protected line normally sees — the TVS stays reverse-biased and invisible until a fault arrives. At 6.45 V breakdown, the device begins conducting; the clamping voltage of 10.5 V at peak pulse current is the ceiling the downstream load never exceeds during a transient event. For a 5 V rail, the 5.8 V standoff gives roughly 13 % margin above the working voltage — adequate for most industrial environments, though a 1N6268 (higher standoff) is the natural next step if you need more headroom. ## Junction temperature range and the through-hole fit The -55 °C to 175 °C junction temperature rating is wide for a general-purpose TVS — the upper bound means the device tolerates self-heating during prolonged clamping events without the junction temperature rising past the reliability ceiling. The DO-201AA (DO-27) axial through-hole package mounts in a standard 0.4-inch lead spacing footprint — the body sits off-board with both leads in plane, which helps thermal conduction along the leads into the PCB pad and the chassis plane. ## Tape & Box packaging — what the storeroom needs to know The -/73 suffix designates tape & box per EIA-481; the component leads are formed to the tape pitch and the reel is boxed for through-hole insertion equipment. No moisture sensitivity rating is listed for this package — the DO-201AA is not a plastic surface-mount part, so dry storage is not a constraint the way it is for MSL-rated SMD reels.","metaTitle":"Vishay 1N6267A-E3/73 TransZorb TVS Diode, 5.8V, 1.5kW","metaDescription":"Vishay 1N6267A-E3/73 unidirectional TVS diode, 5.8V standoff / 6.45V breakdown / 10.5V clamping, 1.5kW peak pulse, DO-201AA axial.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","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":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1N6267","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"6.45V","Voltage - Clamping (Max) @ Ipp":"10.5V","Voltage - Reverse Standoff (Typ)":"5.8V","Current - Peak Pulse (10/1000µs)":"143A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3851","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1N6267A-E3%2F73/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1N6267A-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/1N6267A-E3-73 when reusing this data.
