The ±5% tolerance means the actual breakdown voltage falls between 4.845 V and 5.355 V — tight enough for basic shunt regulation or as a reference in a low-cost supply, but not precise enough for a band-gap-grade voltage reference. ## Zener impedance and leakage Maximum Zener impedance is 7 Ω at the test current (Zzt). This impedance determines how much the output voltage shifts under load: a 10 mA change in Zener current shifts the voltage by roughly 70 mV. Reverse leakage is specified at 10 µA maximum at 1 V reverse bias — well below the breakdown knee, so the diode draws negligible current in the off state. Forward voltage is 1.2 V maximum at 200 mA forward current — a useful number if the diode is occasionally forward-biased in a protection or clamping role. The DO-41 axial-lead package is through-hole mounted — the leads are soldered into plated through-holes on the PCB, making it suitable for prototyping, rework, and builds where vibration resistance is less critical than board-level repairability.","metaTitle":"Microchip 1N4733AP/TR8 Zener Diode, 5.1V, 1W, DO-41","metaDescription":"Microchip Technology 1N4733AP/TR8 Zener diode, 5.1V nominal, 1W power dissipation, ±5% tolerance, DO-204AL (DO-41) axial package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Microchip Technology","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","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":"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":"$2.6100","priceTiers":[{"qty":1,"price":"$2.61000","currency":"USD"},{"qty":1500,"price":"$2.61000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5f236ca5540da5bdb84674abb4a197c3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1N4733AP%2FTR8/alternatives.json"},"ai":{"faq":[{"question":"What package does the 1N4733AP/TR8 come in?","answer":"The 1N4733AP/TR8 is supplied in a DO-204AL (DO-41) axial-lead through-hole package.
