It dissipates 1 W continuously, so the junction temperature rise at full rated power in still air is the limiting factor for derating — a 1 W part in a DO-41 body needs adequate lead length or a heatsink tab if operated near the ceiling in a 70 °C ambient. The ±5% tolerance on the nominal 5.6 V Zener voltage means the actual regulation point for any given unit falls between 5.32 V and 5.88 V at the test current. For a rail that must stay within 5% of 5.6 V, a tighter-binned part or a series resistor adjustment is needed. ## Impedance and leakage — the so-what for the bench Maximum Zener impedance is 5 Ohms at the Zener test current. This dynamic resistance means the output voltage shifts about 5 mV per mA of load change — negligible for a simple shunt regulator but relevant if the diode also serves as a reference for a downstream converter. Reverse leakage is 10 µA max at 2 V reverse bias, well below the Zener knee. At the 5.6 V operating point leakage rises, but the 1 W power rating ensures the diode stays in the avalanche region without thermal runaway under normal bias. Forward voltage is 1.2 V max at 200 mA — the diode conducts as a standard rectifier in the forward quadrant, though the 1 W dissipation limit applies in either direction. ## Temperature range and soldering margin The DO-41 body with tin-plated copper leads withstands wave-solder profiles up to 260 °C peak for 10 seconds without compromising the die attach. Microchip Technology lists this part as Active. The base product number is 1N4734, and the /TR12 suffix denotes Tape & Reel packaging for automated insertion.","metaTitle":"Microchip 1N4734AP/TR12 Zener Diode, 5.6 V, 1 W, DO-41","metaDescription":"Microchip Technology 1N4734AP/TR12 Zener diode, 5.6 V nominal, 1 W power dissipation, ±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":"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":"$1.8150","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f2579cdb7aec091d0b5f99df5459e04c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1N4734AP%2FTR12/alternatives.json"},"ai":{"faq":[{"question":"What package does the 1N4734AP/TR12 come in?","answer":"The diode is housed in a DO-204AL (DO-41) axial-leaded package, supplied on Tape & Reel.
