Breakdown is guaranteed at 31.1V minimum, so the standoff voltage of 28V leaves a 3.1V margin before the diode starts conducting — enough headroom for most 24V to 28V rails without nuisance triggering. ## Clamping voltage and pulse current — the transient budget At the 13.2A peak pulse current (Ipp) the diode clamps at 45.4V maximum. That 45.4V ceiling is what the protected IC's breakdown rating must exceed — a 40V-rated MOSFET on a 28V rail would be marginal; a 60V device gives comfortable margin. The bidirectional channel handles both positive and negative transients with a single device. Microchip lists the SMBJ28CAE3/TR13 as Active. The DO-214AA (SMB) footprint is widely stocked across multiple distributor channels.","metaTitle":"SMBJ28CAE3/TR13 – Microchip 28V Bidirectional TVS, 600W","metaDescription":"SMBJ28CAE3/TR13 Zener TVS diode from Microchip Technology. 28V reverse standoff, 45.4V clamping, 600W peak pulse power, DO-214AA SMB, -65°C to 150°C.","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":"SMBJ28","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)":"31.1V","Voltage - Clamping (Max) @ Ipp":"45.4V","Voltage - Reverse Standoff (Typ)":"28V","Current - Peak Pulse (10/1000µs)":"13.2A"}},"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":"What is the closest pin-compatible alternative to the SMBJ28CAE3/TR13?","answer":"The SMBJ28CA (non- suffix) is the same die in the same DO-214AA package, differing only in lead-finish plating.
