The ±5% tolerance on the nominal voltage means the actual zener voltage at the test current falls between 5.32 V and 5.88 V — a band tight enough for most voltage-reference and clamping circuits without trimming. Maximum impedance (Zzt) is 5 Ohms at the zener test current, which keeps the voltage shift small as the diode current varies within its operating range. The Tape & Reel packaging (TR suffix) feeds directly into automated pick-and-place for through-hole axial insertion — no manual handling step needed for volume builds. ## Temperature grade and environment Operating junction temperature range is -65°C to 150°C — this covers the full industrial and military temperature envelope. The 1 W power rating must be derated above 25°C per the datasheet thermal resistance curve; in a 70°C ambient the usable power drops to roughly 0.7 W without forced airflow.","metaTitle":"Microchip 1N4734APE3/TR12 Zener Diode, 5.6 V, 1 W, DO-41","metaDescription":"Microchip Technology 1N4734APE3/TR12 zener diode, 5.6 V nominal, ±5% tolerance, 1 W power dissipation, DO-204AL (DO-41) axial package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Microchip Technology","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±5%","Power - Max":"1 W","Mounting Type":"Through Hole","Package / Case":"DO-204AL, DO-41, Axial","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"1N4734","Impedance (Max) (Zzt)":"5 Ohms","Operating Temperature":"-65°C~150°C","Supplier Device Package":"DO-204AL (DO-41)","Voltage - Zener (Nom) (Vz)":"5.6 V","Current - Reverse Leakage @ Vr":"10 µA @ 2 V","Voltage - Forward (Vf) (Max) @ If":"1.2 V @ 200 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9150","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f2579cdb7aec091d0b5f99df5459e04c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to 1N4734APE3/TR12?","answer":"The base product number 1N4734 covers multiple suffix variants (e.g., 1N4734A, 1N4734APE3) from Microchip and other manufacturers. All share the same DO-41 package and 5.6 V nominal voltage. The key difference is the tolerance grade — the A-suffix parts are ±5%, while non-A parts are typically ±10%. The PE3/TR12 suffix indicates Microchip's own Pb-free plating and Tape & Reel packaging. Any 1N4734A in DO-41 is a functional drop-in for the same BOM position, but confirm the specific tolerance and packaging before substituting."},{"question":"What compliance documentation does Microchip Technology provide for 1N4734APE3/TR12?","answer":"Microchip Technology provides RoHS and REACH compliance declarations for the PE3 suffix parts. The part is Pb-free and meets the EU RoHS exemption criteria. No UL or IEC certification is typically issued for individual zener diodes — the compliance documentation covers material composition and process conformance. Full certificates are available from Microchip's compliance portal or through the distributor upon request."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N4734APE3-TR12","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N4734APE3-TR12 when reusing this data.
