For a rail that needs tighter than 10% absolute accuracy, a selected or tighter-tolerance part is the safer call. Maximum impedance (Zzt) of 5 Ohms at the test current means the regulation voltage shifts about 5 mV per mA of load current change — a 20 mA swing shifts the output by 100 mV, which is within the tolerance band but worth budgeting in a precision bias supply. ## Power dissipation and thermal margin Rated for 1 W continuous power dissipation in the DO-204AL (DO-41) axial package. At 5.6 V that works out to about 178 mA maximum Zener current — but the real limit is junction temperature, not the current number. ## Leakage and forward conduction Reverse leakage is specified at 10 µA maximum at 2 V reverse bias. That is the off-state current the diode draws before it reaches the Zener knee — negligible for most bias circuits, but worth checking if the load is a high-impedance CMOS input that sees the leakage as an offset. Forward voltage is 1.2 V maximum at 200 mA forward current. When the diode is forward-biased (e.g., in a clamping or protection role), the 1.2 V drop at 200 mA means 240 mW of conduction loss — well within the 1 W budget, but the heat still goes into the same junction.","metaTitle":"Microchip 1N4734P/TR8 Zener Diode, 5.6 V, 1 W, DO-41","metaDescription":"Microchip Technology 1N4734P/TR8 Zener diode, 5.6 V nominal, 1 W power dissipation, ±10% tolerance, 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":"±10%","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":"$1.7850","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f2579cdb7aec091d0b5f99df5459e04c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the tolerance of 1N4734P/TR8?","answer":"The Zener voltage tolerance is ±10%, so a 5.6 V nominal diode regulates between 5.04 V and 6.16 V."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N4734P-TR8","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N4734P-TR8 when reusing this data.
