When a transient exceeds that threshold, it clamps the overvoltage at 77.4 V maximum, protecting whatever sits behind it from the spike. Bidirectional (the CA suffix) means it clamps both polarities — suitable for AC signal rails or any line where the clamped voltage stays below the downstream absolute maximum at both polarities. The junction temperature rating of -55°C to 150°C gives plenty of margin for industrial enclosures that run hot, or for automotive under-hood adjacent panels that see cold soak and heat cycles. ## Package and what it means for board integration The DO-214AB SMC is the industry-standard high-power TVS footprint — pin-compatible parts are available from multiple brands, and it is a standard pick-and-place package. The cathode band marks polarity on the standard orientation. Reflow profile follows the standard tin-lead or lead-free reflow schedule for the package size; a hot-air rework tool handles field swaps without special tooling. ## What the series and ratings say about fit The 1.5SMCJ series is the 1500 W peak-pulse class — one step below the 3.0SMCJ series (3000 W) in the same SMC package, so a buyer cross-shopping on power will find it is the mid-range option in this footprint. The spec sheet lists general purpose applications with power line protection marked No — this is a signal and control line transient suppressor, not a mains-supply clamp, which is the key distinction if someone is evaluating it for a power rail protection role. No stock-holding claim is made; the sourcing posture is BOM-driven quotation against the listed order code.","metaTitle":"Panjit 1.5SMCJ48CA_R1_00001 TVS Diode, 48V Standoff, SMC","metaDescription":"Panjit 1.5SMCJ48CA_R1_00001 unidirectional TVS diode, 48V standoff, 77.4V clamping at 19.4A, 1.5kW peak pulse, DO-214AB SMC package.","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","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMC (DO-214AB)","Voltage - Breakdown (Min)":"53.3V","Voltage - Clamping (Max) @ Ipp":"77.4V","Voltage - Reverse Standoff (Typ)":"48V","Current - Peak Pulse (10/1000µs)":"19.4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a271c765b4bf7e62ca251a7791548580.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMCJ48CA_R1_00001/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/panjit-international-inc/1.5SMCJ48CA_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/1.5SMCJ48CA_R1_00001 when reusing this data.
