Overview
The onsemi 1N4750A is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 27 V with a tolerance of ±5%. The device dissipates up to 1 W of power and operates within a temperature range of -65 °C to +200 °C. Key electrical parameters include a maximum reverse leakage current of 5 µA, a Zener impedance of 35 Ohms, and a test current of 9.5 mA. It utilizes a DO-41-2 through-hole package.
Feature Summary
- Provides stable voltage regulation at a nominal 27 V level
- Capable of handling 1 W power dissipation in a compact axial leaded package
- Operates reliably across an extended industrial temperature range
Applications
- Voltage reference circuits
- Overvoltage protection
- Clipping and clamping applications
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm exact mechanical or electrical variations. Ensure compatibility with existing PCB footprints, specifically the DO-41-2 package dimensions. Confirm RoHS compliance status and REACH SVHC declarations prior to integration into final assemblies.
Selection Notes
Select this component when a standard 27 V regulation point is required with moderate precision. Consider the thermal resistance and mounting style if operating near maximum power limits. Verify that the 35 Ohm impedance meets the dynamic regulation requirements of the target circuit design.
Part Context
This part belongs to the widely used 1N47xx series of 1 Watt Zener diodes. These components are standard industry references for low-cost voltage regulation. The 1N4750A specifically targets the 27 V segment of this family, offering a balance between voltage stability and cost-effectiveness for general-purpose electronic designs.
Replacement Considerations
Cross-reference with other manufacturers' 1N4750A equivalents such as those from Rectron, Panjit, or Microchip. Ensure substitute parts match the 27 V nominal voltage, 1 W power rating, and DO-41 package form factor.
