Breakdown occurs at a minimum of 14.4V, providing a guard band of roughly 1.4V above the standoff before avalanche conduction begins. Clamping voltage maxes at 23.8V when the diode conducts 21A peak pulse current. That clamp figure determines the voltage stress on a protected IC's absolute maximum rating — ensure the protected device's max rating exceeds 23.8V with margin. Operating junction temperature spans -65°C to 150°C, making this TVS suitable for environments with wide thermal swings — engine bay, outdoor telecom cabinets, or industrial enclosures where ambient can exceed 85°C. No power line protection means it is not intended for AC mains surge suppression. ## Active production and procurement posture","metaTitle":"SMAJ13E3/TR13 TVS Diode – 13V Standoff, 500W Peak Pulse","metaDescription":"SMAJ13E3/TR13 Zener TVS from Microchip Technology. 13V reverse standoff, 14.4V breakdown, 23.8V clamping at 21A. 500W peak pulse power in DO-214AC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Microchip Technology","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AC, SMA","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"500W","Base Product Number":"SMAJ13","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AC (SMA)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"14.4V","Voltage - Clamping (Max) @ Ipp":"23.8V","Voltage - Reverse Standoff (Typ)":"13V","Current - Peak Pulse (10/1000µs)":"21A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7b3ddece4863b4621debe180df56adc8.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMAJ13E3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMAJ13E3-TR13 when reusing this data.
