Housed in a standard DO-41 (DO-204AL) axial-lead package, this through-hole component features a nominal Zener voltage (Vz) of 33 V with a tight tolerance of ±5%. Engineered for robust performance, the device supports a maximum power dissipation of 1 W at ambient temperatures up to 50°C and maintains functional stability at junction temperatures reaching 200°C. Electrically, the 1N4752A exhibits a sharp reverse characteristic and low reverse leakage current, with a maximum leakage of 5 µA at 25.1 V. The device is characterized by a maximum Zener impedance of 45 Ω at a test current (Izt) of 7.5 mA, ensuring stable voltage regulation across varying load conditions. With a maximum forward voltage drop of 1.2 V at 200 mA, this diode is well-suited for industrial power supply circuits, signal conditioning, and general-purpose voltage clamping where thermal management and consistent breakdown performance are required. ## Specifications | Parameter | Value | |---|---| | Svhc | Lead (25-Jun-2025) | | No. Of Pins | 2Pins | | Product Range | - | | Qualification | - | | Diode Mounting | Through Hole | | Diode Case Style | DO-41 (DO-204AL) | | Power Dissipation | 1W | | Zener Voltage Nom | 33V | | Operating Temperature Max | 200°C | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:2675156/) ## **Zener Diodes** ## **Features** - High reliability - Very sharp reverse characteristic - Low reverse current level - Vz-tolerance ±5% ## **Application** Voltage stabilization ## **Absolute Maximum Ratings Tj = 25°C** |**Parameter**|**Test Conditions**|**Symbol**|**Value**|**Unit**| |---|---|---|---|---| |Power dissipation|Tamb≤ 50°C|Pv|1|W| |Z-current|-|Iz|Pv / Vz|mA| |Junction temperature|-|Tj|200|°C| |Storage temperature range|-|Tstg|-65 to +175|| **Maximum Thermal Resistance Tj = 25°C** **Parameter Test Conditions Symbol Value Unit** ~~ee~~ Junction ambient I = 9.5 mm (3/8") TL = constant Rthja 100 k/W Stresses exceeding maximum ratings may damage the device.
