The ±5% tolerance means the actual zener voltage lands between 7.125 V and 7.875 V at the test current — tight enough for a reference rail in a linear regulator or a clamp in a low-voltage supply. ## Dynamic impedance and leakage — the so-what Maximum zener impedance (Zzt) is 4 Ohms at the nominal 7.5 V point. That low dynamic resistance means the diode holds its regulation voltage within a few tens of millivolts as the bias current varies — useful when the same zener is both a reference and a load-dump clamp. Reverse leakage is 10 µA at 5 V, which is below the bias current of most shunt regulators, so it won't pull the reference node down in a high-impedance divider. Forward voltage is 1.2 V max at 200 mA — the diode can handle brief forward surges, but the 1 W dissipation limit governs continuous forward current.","metaTitle":"Microchip 1N4737APE3/TR12 Zener Diode, 7.5V, 1W, DO-41","metaDescription":"Microchip Technology 1N4737APE3/TR12 zener diode, 7.5V nominal, ±5% tolerance, 1W 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":"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":"$0.9150","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f2579cdb7aec091d0b5f99df5459e04c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What package does the 1N4737APE3/TR12 come in?","answer":"It is supplied in the DO-204AL (DO-41) axial-lead package, on Tape & Reel (TR).
