This is the choice for AC lines, differential signal pairs, or any circuit where the rail can be driven both positive and negative relative to ground. The unidirectional UA variant in the same series clamps only one polarity and is wrong for those applications — same footprint, opposite clamping behavior, and the BOM line must reflect which one was specified. ## Standoff, breakdown, and clamping — the three voltages that size the protection 53 V reverse standoff (typ) is the maximum reverse voltage the TVS can block indefinitely without conducting — transients above this level trigger the clamp. The 58.9 V minimum breakdown voltage marks where conduction begins. At full peak pulse current the clamping voltage is held to 85 V maximum, which is the ceiling the downstream circuitry must withstand — this is the number circuit designers use when they calculate the stress on the protected node. The 1500 W peak pulse power rating reflects the energy the diode absorbs during that event — at 85 V clamping × 17.6 A the math works out to approximately 1.5 kW, confirming the waveform condition governs the rating rather than a generic abs-max. ## Package, thermal range, and deployment fit DO-214AB (SMC) is the surface-mount package — the pad layout matches the industry-standard SMC footprint used by multiple TVS suppliers, so existing board artwork from a Bourns or Littlefuse SMDB footprint drops straight in without a respin. Mounted in tape and reel (TR), the part is assembled by pick-and-place — the 1.5SMC62 base product number covers a wide range of stand-off voltages in the same package, so a board respin looking for a tighter or wider protection window can search across the series without changing footprint or layout.","metaTitle":"1.5SMC62CA-M3/57T TVS Diode, 85 V Clamping","metaDescription":"Vishay 1.5SMC62CA-M3/57T bidirectional TVS diode, 53 V standoff, 58.9 V min breakdown, 85 V clamping at 17.6 A, 1500 W peak pulse, DO-214AB SMC.","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":"1.5SMC, TransZorb®","Package":"Tape & Reel (TR)","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":"1.5SMC62","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMCJ)","Voltage - Breakdown (Min)":"58.9V","Voltage - Clamping (Max) @ Ipp":"85V","Voltage - Reverse Standoff (Typ)":"53V","Current - Peak Pulse (10/1000µs)":"17.6A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4447","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/de7dd597f6fdc3f56660f78f3e5a960d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC62CA-M3%2F57T/alternatives.json"},"ai":{"faq":[{"question":"What does the CA suffix in 1.5SMC62CA-M3/57T mean?","answer":"The CA suffix designates the bidirectional polarity variant of this TVS series — it clamps transients in both the positive and negative direction.
