Packaged in a SQ-MELF B case (surface-mount), it suits board-level transient protection where a through-hole part won't fit the assembly process. ## Junction temperature and operating envelope Rated for junction temperatures from -55°C to 175°C, the 1N6137AUS handles the thermal extremes of avionics, industrial drives, and outdoor telecom equipment. The 190 V minimum breakdown voltage gives a guard band below the 273 V clamp — the designer sizes the TVS so the protected circuit's absolute-max rating stays above the clamp level. ## Active production and sourcing posture The SQ-MELF B package is a standard footprint, widely available through distribution.","metaTitle":"1N6137AUS Zener TVS Diode – 500 W, 152 V Standoff, SQ-MELF","metaDescription":"1N6137AUS Zener transient voltage suppressor from Microchip Technology. 500 W peak pulse power, 152 V reverse standoff, bidirectional, SQ-MELF surface mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Microchip Technology","Type":"Zener","Series":"-","Package":"Bulk","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"SQ-MELF, B","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"500W","Base Product Number":"1N6137","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"B, SQ-MELF","Voltage - Breakdown (Min)":"190V","Voltage - Clamping (Max) @ Ipp":"273V","Voltage - Reverse Standoff (Typ)":"152V","Current - Peak Pulse (10/1000µs)":"1.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.2400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5dbd5050221203b922ebce5a7a6e86e6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the 1N6137AUS a bidirectional device?","answer":"Yes, the 1N6137AUS is a single bidirectional channel — it clamps both polarities with one junction, which saves board space compared to back-to-back unidirectional diodes."},{"question":"What is the 1N6137AUS's peak pulse current rating?","answer":"1.8 A peak pulse current measured with a 10/1000 µs waveform at the 273 V clamping voltage."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N6137AUS","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N6137AUS when reusing this data.
