Above 53.3V the diode begins to avalanche, and at 77.4V it clamps the transient to that ceiling, shunting the surge current through the device. This simplifies BOM and board layout for AC-coupled signals or bipolar supply lines where polarity is not fixed. ## Temperature range and package — DO-214AA SMB on tape and reel The DO-214AA (SMB) package is a surface-mount footprint compatible with standard reflow profiles.","metaTitle":"SMBJ48CAE3/TR13 Zener TVS Diode, 48V Bidirectional, DO-214AA","metaDescription":"SMBJ48CAE3/TR13 bidirectional Zener TVS diode, 48V reverse standoff, 53.3V breakdown, 77.4V clamp at 7.7A, 600W peak pulse, DO-214AA SMB, active production.","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-214AA, SMB","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"600W","Base Product Number":"SMBJ48","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMBJ (DO-214AA)","Voltage - Breakdown (Min)":"53.3V","Voltage - Clamping (Max) @ Ipp":"77.4V","Voltage - Reverse Standoff (Typ)":"48V","Current - Peak Pulse (10/1000µs)":"7.7A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f566c62ad8bf6be9ecf452f6999d0b7a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SMBJ48CAE3/TR13 bidirectional or unidirectional?","answer":"It is a single bidirectional channel, clamping both positive and negative transients.
