The ±5% tolerance on the nominal 7.5 V Zener voltage means the actual regulation point sits between 7.125 V and 7.875 V at the specified test current — a figure to budget into the output rail tolerance for the downstream load. Maximum Zener impedance is 4 Ohms (Zzt), which defines the incremental resistance at the operating point; a lower impedance gives tighter regulation as the load current varies, and this value is typical for a 1 W device at this voltage. ## Temperature range and leakage Reverse leakage is specified at 10 µA maximum with 5 V reverse bias — well below the Zener knee, so standby power loss in a reverse-biased shunt configuration stays under 50 µW per diode. Forward voltage drop is 1.2 V maximum at 200 mA forward current, a parameter that matters if the diode sees brief forward conduction in a bidirectional clamp topology.","metaTitle":"Microchip 1N4737AP/TR8 Zener Diode, 7.5 V, 1 W, DO-41","metaDescription":"Microchip Technology 1N4737AP/TR8 Zener diode, 7.5 V nominal, 1 W, ±5% 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":"±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":"1N4737","Impedance (Max) (Zzt)":"4 Ohms","Operating Temperature":"-65°C ~ 150°C","Supplier Device Package":"DO-204AL (DO-41)","Voltage - Zener (Nom) (Vz)":"7.5 V","Current - Reverse Leakage @ Vr":"10 µA @ 5 V","Voltage - Forward (Vf) (Max) @ If":"1.2 V @ 200 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5f236ca5540da5bdb84674abb4a197c3.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N4737AP-TR8","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N4737AP-TR8 when reusing this data.
