The ±2% tolerance on the nominal voltage means the regulation window is ±150 mV — tighter than the common ±5% grade, so it holds the reference rail closer for precision biasing or clamping circuits. Rated for 1 W continuous power dissipation, the part can sink steady-state current up to about 133 mA at 7.5 V before the junction temperature hits the derating limit. Packaged in Tape & Reel (TR), it ships in volume quantities suited for automated pick-and-place or through-hole insertion lines. The DO-204AL (DO-41) axial footprint is a decades-old industry standard, so replacement sourcing from other manufacturers is straightforward if a second-source hedge is needed.","metaTitle":"Microchip 1N4737CE3/TR13 Zener Diode, 7.5 V, 1 W, DO-41","metaDescription":"Microchip Technology 1N4737CE3/TR13 Zener diode, 7.5 V nominal, ±2% 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":"±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":"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":"$1.1250","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f2579cdb7aec091d0b5f99df5459e04c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the tolerance and power rating of 1N4737CE3/TR13?","answer":"The Zener voltage tolerance is ±2%, and the maximum power dissipation is 1 W.
