When a transient exceeds the breakdown threshold, the device clamps the output to a defined let-through level, absorbing up to 1500 W peak pulse without damage. ## What the clamping and breakdown specs mean in-circuit Minimum breakdown is 209 V — once the transient crosses that threshold the TVS enters conduction and the clamping network takes over. A 4.8 A peak pulse current at 308 V clamping is consistent with the 1500 W peak pulse rating — those three numbers are linked by the same transient event. The DO-214AB (SMC) package is the standard foot-print for this power class; land-pattern and solder-joint geometry are driven by the 1.5 kW transient rating and the thermal path from junction to PCB pad.","metaTitle":"1.5SMCJ190A_R1_00001 TVS Diode, 190V standoff","metaDescription":"Panjit 1.5SMCJ190A_R1_00001 unidirectional Zener TVS, 190V standoff / 209V breakdown / 308V clamping, 1500W peak pulse, -55°C to 150°C junction.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Panjit International Inc.","Type":"Zener","Series":"1.5SMCJ","Package":"Tape & Reel (TR) Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC","Operating Temperature":"-55°C ~ 150°C (TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SMC (DO-214AB)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"209V","Voltage - Clamping (Max) @ Ipp":"308V","Voltage - Reverse Standoff (Typ)":"190V","Current - Peak Pulse (10/1000µs)":"4.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a271c765b4bf7e62ca251a7791548580.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What series does the 1.5SMCJ190A_R1_00001 belong to?","answer":"It is part of the 1.5SMCJ series — a Panjit family of unidirectional Zener TVS diodes in the DO-214AB SMC package, rated for general-purpose transient protection across a range of standoff voltages."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/panjit-international-inc/1.5SMCJ190A_R1_00001","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/panjit-international-inc/1.5SMCJ190A_R1_00001 when reusing this data.
