Bidirectional construction means a single device handles both positive and negative surges — no polarity concern on AC signal lines, telecom pairs, or bipolar power rails. ## Active lifecycle — no last-time-buy clock Microchip lists the SMBJ78CAE3/TR13 as Active. Housed in the DO-214AA (SMB) surface-mount package, the SMBJ78CAE3/TR13 shares the same footprint as the SMBJ (DO-214AA) supplier device package. The SMB body is smaller than the SMC but larger than the SOD-123 — it balances surge capability with board area. The copper pad area under the cathode tab on the PCB sets the thermal resistance; a 1 oz copper pad of at least 25 mm² per the typical layout keeps junction temperature rise within limits during repetitive surge events.","metaTitle":"SMBJ78CAE3/TR13 TVS Diode – 78V Bidirectional, 600W","metaDescription":"SMBJ78CAE3/TR13 bidirectional TVS diode from Microchip Technology. 78V standoff, 86.7V breakdown, 126V clamp, 600W peak pulse power.","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":"SMBJ78","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)":"86.7V","Voltage - Clamping (Max) @ Ipp":"126V","Voltage - Reverse Standoff (Typ)":"78V","Current - Peak Pulse (10/1000µs)":"4.7A"}},"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":"What is the closest pin-compatible alternative to SMBJ78CAE3/TR13 in this Circuit Protection family?","answer":"The base product number SMBJ78 covers the same DO-214AA package and 78V standoff family. The SMBJ78A (unidirectional) and SMBJ78CA (bidirectional) share the same footprint and voltage ratings — the difference is the number of TVS junctions.
