The 42.1V clamping voltage limits the spike the downstream IC sees. No need to series two unidirectional parts. ## Clamping voltage and peak current – the margin check The 42.1V clamp at 14.2A peak pulse current is the worst-case voltage the protected circuit sees. Compare that against the absolute-maximum rating of the downstream IC — a 40V-rated switching regulator has 2.1V of headroom; a 36V-rated part does not. The 600W peak pulse rating assumes a 10/1000 µs waveform. For shorter pulses (e.g. 8/20 µs) the peak power capability is higher — the datasheet derating curve shows the multiplier, but the 600W figure is the baseline for BOM comparison. Microchip lists this part as Active. Supplied on tape & reel — standard for automated pick-and-place. The - suffix indicates RoHS-compliant and halogen-free construction.","metaTitle":"SMBJ26CAE3/TR13 TVS Diode – 600W Bidirectional Zener","metaDescription":"Microchip Technology SMBJ26CAE3/TR13 bidirectional Zener TVS diode. 26V reverse standoff, 42.1V 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":"SMBJ26","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)":"28.9V","Voltage - Clamping (Max) @ Ipp":"42.1V","Voltage - Reverse Standoff (Typ)":"26V","Current - Peak Pulse (10/1000µs)":"14.2A"}},"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":"Is SMBJ26CAE3/TR13 a bidirectional TVS diode?","answer":"Yes — it is a single bidirectional channel, clamping both positive and negative transients on the same line.
