Breakdown occurs at 8.33V minimum, and the clamping voltage is held to 14.3V at the peak pulse current of 35A. That 14.3V ceiling is what matters for downstream IC survival — the rail sees no more than that during the surge event. The wide Tj range also means derating at elevated temperatures is less aggressive than with commercial-grade parts. Listed as Active, the SMAJ7.5E3/TR13 is in ongoing production at Microchip.","metaTitle":"SMAJ7.5E3/TR13 – Microchip Zener TVS, 7.5V, 500W, DO-214AC","metaDescription":"SMAJ7.5E3/TR13 Zener TVS diode from Microchip, 7.5V reverse standoff, 500W peak pulse, DO-214AC (SMA).

We source it through franchised and authorized distribution channels. Submit an RFQ with your target quantity and lead-time requirement; we confirm availability and current pricing at quote time."},{"question":"Is SMAJ7.5E3/TR13 unidirectional or bidirectional?","answer":"It is a unidirectional device — one channel. The cathode band on the DO-214AC package marks the ground side; the anode connects to the protected rail."},{"question":"Can SMAJ7.5E3/TR13 replace SMAJ7.5A?","answer":"The base product number is SMAJ7.5. The '' suffix indicates Microchip's lead-free / RoHS-compliant finish. The 'A' suffix on other variants typically denotes a different tolerance on breakdown voltage. Check the specific datasheet for the SMAJ7.5A to confirm electrical equivalence — the package and footprint are the same DO-214AC."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMAJ7.5E3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMAJ7.5E3-TR13 when reusing this data.
