The ±5% tolerance on the nominal Zener voltage means the regulation window spans 4.845 V to 5.355 V — tight enough for most 5 V rail clamping or reference applications without requiring a precision-grade part. The 1 W power rating sets the maximum steady-state dissipation: at 5.1 V, the diode can conduct up to about 196 mA before exceeding the thermal limit at 25°C ambient. The 7 Ohm max Zzt impedance at the Zener test current means the regulation voltage shifts roughly 70 mV per 10 mA of bias current change — a consideration for circuits where the load current varies widely. Reverse leakage is specified at 10 µA maximum at 1 V reverse bias — well below the Zener knee, confirming the diode is fully off below the regulation voltage. The forward voltage drop of 1.2 V at 200 mA is a standard silicon junction characteristic — the diode conducts in the forward direction like a conventional rectifier when the anode is positive, which matters for circuits that use the Zener in a bidirectional clamping configuration.","metaTitle":"Microchip 1N4733AP/TR12 Zener Diode, 5.1 V, 1 W, DO-41","metaDescription":"Microchip Technology 1N4733AP/TR12 Zener diode, 5.1 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":"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":"$1.8150","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f2579cdb7aec091d0b5f99df5459e04c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1N4733AP%2FTR12/alternatives.json"},"ai":{"faq":[{"question":"What is the tolerance and power rating of the 1N4733AP/TR12?","answer":"The Zener voltage tolerance is ±5%, and the maximum power dissipation is 1 W.
