The bidirectional channel eliminates orientation concerns on AC or bipolar signal lines. ## Clamping voltage and pulse current — what they mean for rail protection The 12.9 V clamping ceiling at 38.8 A peak pulse current sets the voltage stress the downstream circuitry must survive during a transient. For a 7.5 V supply, the clamp sits about 5.4 V above the rail — typical for a 500 W TVS at this voltage class. ## Active production — tape & reel for volume assembly Microchip lists the SMAJ7.5CAE3/TR13 as Active, meaning ongoing production with no announced end-of-life.","metaTitle":"SMAJ7.5CAE3/TR13 – Microchip 500W Bidirectional Zener TVS","metaDescription":"SMAJ7.5CAE3/TR13 from Microchip: 500W peak pulse power, 7.5V reverse standoff, bidirectional Zener TVS in DO-214AC (SMA) package.","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":"SMAJ7.5","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)":"8.33V","Voltage - Clamping (Max) @ Ipp":"12.9V","Voltage - Reverse Standoff (Typ)":"7.5V","Current - Peak Pulse (10/1000µs)":"38.8A"}},"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":"Can SMAJ7.5CAE3 replace SMAJ7.5A?","answer":"The SMAJ7.5A is a unidirectional version of the same 7.5 V TVS in the same DO-214AC package. The SMAJ7.5CAE3 is bidirectional — it clamps both polarities.
