Overview
The onsemi 1N4750A-T50A is a silicon planar Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 27 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W and operates within a temperature range of -65 °C to +200 °C. Packaged in the DO-41 axial leaded format, it exhibits a maximum reverse leakage current of 5 µA and a Zener impedance of 35 Ohms at a test current of 9.5 mA.
Feature Summary
- Provides stable voltage regulation using silicon planar technology
- Capable of handling high thermal loads with an extended operating temperature range up to 200 °C
- Utilizes a robust DO-41 axial package suitable for through-hole mounting
Applications
- Voltage reference circuits requiring precise potential levels
- Overvoltage protection stages in electronic systems
- General-purpose voltage regulation tasks
Procurement Notes
Verify the specific suffix T50A against official datasheets to confirm packaging details and manufacturing origin. Ensure compatibility with existing board layouts regarding the DO-41 footprint dimensions. Cross-reference electrical parameters such as Zener impedance and leakage current with design requirements before finalizing procurement decisions.
Selection Notes
Select this component when a 27 V regulation point is required with standard 5% tolerance. Consider the 1 W power rating and wide temperature capability for demanding environments. Verify that the axial lead configuration aligns with the assembly process and mechanical constraints of the target application.
Part Context
This part belongs to the widely recognized 1N47xx series of Zener diodes, which are industry-standard components for low-to-medium power voltage regulation. The 1N4750 variant specifically targets the 27 V segment, offering a balance between performance and cost-effectiveness for general industrial and commercial electronics.
Replacement Considerations
Compatible substitutes include the 1N4750A from other manufacturers such as Rectron or Panjit, provided they meet the same 27 V, 1 W, and DO-41 specifications. Ensure any replacement maintains equivalent electrical characteristics and thermal ratings.
