1N4750A R1G

Overview

The Taiwan Semiconductor 1N4750A R1G 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 is rated for a maximum power dissipation of 1 W and operates within a temperature range from -65 °C to +200 °C. Packaged in the DO-41 axial leaded format, it exhibits a maximum reverse leakage current of 5 uA and a Zener impedance of 35 Ohms at a test current of 9.5 mA.

Feature Summary

• Provides stable voltage regulation through a passivated junction design suitable for general-purpose applications.
• Capable of handling high thermal loads with an extended maximum operating temperature rating up to 200 °C.
• Utilizes a robust DO-41 through-hole package to ensure reliable mechanical mounting and electrical connectivity.

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• General-purpose clipping and clamping configurations

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact packaging and compliance status. Ensure that the requested component matches the required thermal and electrical specifications for the intended circuit environment before finalizing procurement orders.

Selection Notes

Select this component when a 27 V regulation point is required with standard 5% tolerance. Consider the DO-41 package constraints for board layout and verify that the 1 W power dissipation capability aligns with the expected thermal conditions of the application environment.

Part Context

This part belongs to the widely recognized 1N47xxA series of Zener diodes manufactured by Taiwan Semiconductor. These components are standardized for industrial use, offering consistent performance characteristics across various voltage ratings within the same product family line.

Replacement Considerations

Cross-reference with other manufacturers' 1N4750A equivalents to ensure pinout compatibility and matching electrical parameters such as Zener voltage and power rating before substituting.
