Rated for 1500W peak pulse power per the 10/1000 µs waveform, it clamps at 85.5V maximum while handling 17.5A peak pulse current. That combination suits it for industrial 48V bus protection, telecom rectifier outputs, or battery-backed DC supplies where the surge energy is moderate but the rail voltage is well above the 12V/24V common range. ## DO-214AB (SMC) package — surface-mount footprint Housed in the DO-214AB (SMC) package, the SMCJ48E3/TR13 offers a compact surface-mount solution with the supplier device package also designated DO-214AB (SMCJ). The SMC body size is larger than the smaller SMA/SMB siblings, which helps dissipate the heat from repeated surge events — a practical consideration when the TVS is placed near the input connector on a 48V board. Operating temperature range from -65°C to 150°C covers the full industrial and automotive under-hood envelope — no derating concern for outdoor or engine-bay placement. Microchip lists the SMCJ48E3/TR13 as Active, meaning no end-of-life notice is pending and standard factory lead times apply.","metaTitle":"SMCJ48E3/TR13 TVS Diode – 48V Standoff, 1.5kW","metaDescription":"SMCJ48E3/TR13 from Microchip Technology: 48V reverse standoff, 85.5V clamp, 17.5A peak pulse, unidirectional, 1500W, DO-214AB.","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-214AB, SMC","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"SMCJ48","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMCJ)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"53.3V","Voltage - Clamping (Max) @ Ipp":"85.5V","Voltage - Reverse Standoff (Typ)":"48V","Current - Peak Pulse (10/1000µs)":"17.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5550","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is SMCJ48E3 unidirectional or bidirectional?","answer":"It is unidirectional with 1 channel. Use it on a DC rail where the cathode is connected to the positive supply and the anode to ground.
