The single bidirectional channel means it handles surges that swing positive or negative relative to ground, which is useful on AC-coupled signal lines or differential pairs where the common-mode voltage can shift. ## Clamping voltage and current — the real-world margin At the peak pulse current of 17.6A (10/1000µs), the voltage clamps to 28.8V max. That 28.8V ceiling is what the downstream IC sees during a surge — if the protected device's absolute-max rating is below that, you need a lower-clamp part or a second stage. The 500W rating is the product of clamp voltage and peak current; for shorter pulses the power capability goes up, but the datasheet derating curve is the final word. Microchip lists the SMAJ16CE3/TR13 as Active. Surface-mount DO-214AC (SMA) — the same two-pad footprint used across the SMAJ series.","metaTitle":"SMAJ16CE3/TR13 – 16V Bidirectional TVS, 500W, DO-214AC","metaDescription":"SMAJ16CE3/TR13 bidirectional Zener TVS diode, 16V standoff, 17.8V breakdown, 28.8V clamp at 17.6A, 500W 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-214AC, SMA","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"500W","Base Product Number":"SMAJ16","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)":"17.8V","Voltage - Clamping (Max) @ Ipp":"28.8V","Voltage - Reverse Standoff (Typ)":"16V","Current - Peak Pulse (10/1000µs)":"17.6A"}},"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 SMAJ16CE3 a bidirectional TVS diode?","answer":"Yes — it has one bidirectional channel, meaning it clamps surges in both polarities relative to ground."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMAJ16CE3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMAJ16CE3-TR13 when reusing this data.
