At the peak pulse current of 10.3 A (10/1000 µs waveform), the clamping voltage reaches 48.4 V — so the protected circuitry must tolerate that peak during a surge event. The single bidirectional channel simplifies BOM for AC-coupled lines or signal pairs where polarity reverses — no need to orient the diode. ## Pulse power and temperature range — design margin check Power line protection is not provided — this part is for signal or low-power DC rails, not AC mains or high-energy surge paths. If your application sees repetitive high-energy transients, a higher-power TVS or a separate MOV/varistor is needed. The DO-214AC footprint is widely used, so cross-referencing to other manufacturers' 30 V bidirectional TVS diodes is straightforward if a second source is needed.","metaTitle":"SMAJ30CAE3/TR13 – Microchip 30V Bidirectional TVS Diode","metaDescription":"SMAJ30CAE3/TR13 bidirectional Zener TVS, 30V standoff, 33.3V breakdown, 48.4V clamp at 10.3A. 500W peak pulse, -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-214AC, SMA","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"500W","Base Product Number":"SMAJ30","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AC (SMA)","Voltage - Breakdown (Min)":"33.3V","Voltage - Clamping (Max) @ Ipp":"48.4V","Voltage - Reverse Standoff (Typ)":"30V","Current - Peak Pulse (10/1000µs)":"10.3A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7b3ddece4863b4621debe180df56adc8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SMAJ30CAE3/TR13 bidirectional or unidirectional?","answer":"It is a single bidirectional channel.
