The ±2% tolerance on the nominal zener voltage makes this part suitable for reference or clamping applications where a tighter regulation band is required than the standard 5% or 10% grades of the 1N4733 family. With a maximum zener impedance of 7 Ohms at the test current, the regulation accuracy holds across a moderate current range. The 10 µA reverse leakage at 1 V reverse voltage is low for a 5.1 V device, which matters in battery-powered or high-impedance bias circuits where leakage current directly affects the operating point. ## Temperature Range and Package — Deployment Context The DO-204AL (DO-41) axial package with through-hole mounting is a standard footprint for point-to-point wiring, PCB through-hole assembly, or terminal-strip integration in power supplies, voltage references, and protection clamps. Supplied in Tape & Reel (TR) packaging, this variant is suited for automated insertion equipment in medium-to-high volume production.","metaTitle":"Microchip 1N4733CPE3/TR12 Zener Diode, 5.1 V, 1 W, ±2%","metaDescription":"Microchip Technology 1N4733CPE3/TR12 zener diode, 5.1 V nominal, 1 W power dissipation, ±2% 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":"±2%","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":"1N4733","Impedance (Max) (Zzt)":"7 Ohms","Operating Temperature":"-65°C~150°C","Supplier Device Package":"DO-204AL (DO-41)","Voltage - Zener (Nom) (Vz)":"5.1 V","Current - Reverse Leakage @ Vr":"10 µA @ 1 V","Voltage - Forward (Vf) (Max) @ If":"1.2 V @ 200 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f2579cdb7aec091d0b5f99df5459e04c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1N4733CPE3%2FTR12/alternatives.json"},"ai":{"faq":[{"question":"What is the tolerance of the 1N4733CPE3/TR12 zener voltage?","answer":"The nominal zener voltage is 5.1 V with a ±2% tolerance, tighter than the standard 5% or 10% grades of the 1N4733 family.
