Breakdown voltage starts at 178V min, so the part begins conducting well before the clamp voltage is reached — that margin gives the TVS time to turn on hard before the rail hits 259V. The 1.9A peak pulse current rating (10/1000µs) tells you the diode can handle a sustained surge of that amplitude without failing short. ## Junction temperature and field reliability No derating needed at the high end — the silicon is rated for full 500W peak pulse at 150°C junction. No exposed pad, no special thermal vias — just a two-pad land pattern that any pick-and-place line handles. Polarity marking is clear: the cathode band faces the rail side. Microchip lists this part as Active. Supplied in Tape & Reel (TR) — the /TR13 suffix indicates 13-inch reel, standard 3000-piece quantity for DO-214AC.","metaTitle":"SMAJ160AE3/TR13 Zener TVS Diode 500W 160V DO-214AC","metaDescription":"SMAJ160AE3/TR13 Zener TVS, 160V reverse standoff, 178V min breakdown, 259V clamp, 500W peak pulse, DO-214AC, active production.","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":"SMAJ160","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AC (SMA)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"178V","Voltage - Clamping (Max) @ Ipp":"259V","Voltage - Reverse Standoff (Typ)":"160V","Current - Peak Pulse (10/1000µs)":"1.9A"}},"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 SMAJ160AE3/TR13 unidirectional or bidirectional?","answer":"Unidirectional — one channel, cathode band marked on the package.
