1N5231B A0G

Single Zener Diodes Overview

The Taiwan Semiconductor Corporation 1N5231B A0G is a silicon unidirectional voltage regulator diode with a nominal Zener voltage of 5.1 V and a power dissipation rating of 0.5 W (500 mW). It features a 5% voltage tolerance and utilizes the DO-35 axial leaded glass package. The device is designed for through-hole mounting and operates as a single-element rectifier component.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a fixed 5.1 V reference point
• Utilizes hermetically sealed glass encapsulation for environmental protection
• Supports standard through-hole PCB mounting configurations

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Overvoltage protection for sensitive components
• Reference voltage generation in power supplies

Single Zener Diodes Procurement Notes

Verify the specific manufacturer designation, as the base part number appears across multiple vendors including Microchip and New Jersey Semiconductor. Confirm that the A0G suffix corresponds to the Taiwan Semiconductor variant. Ensure the procurement documentation explicitly lists the 5.1 V Zener voltage and 0.5 W power rating to avoid confusion with similar series devices.

Single Zener Diodes Selection Notes

Select this component when a 5.1 V regulated voltage is required in a through-hole assembly. The DO-35 package offers a compact form factor suitable for general-purpose electronics. Consider the 5% tolerance for applications requiring moderate precision. Verify thermal management requirements for the 0.5 W dissipation limit in the final enclosure design.

Single Zener Diodes Part Context

This component belongs to the 1N52xx series of Zener diodes, widely used for basic voltage clamping and regulation. The 1N5231B designation specifically identifies the 5.1 V variant within this family. The A0G suffix denotes the specific packaging and compliance configuration provided by Taiwan Semiconductor Corporation.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5231B parts, such as those from Microchip or New Jersey Semiconductor, ensuring identical 5.1 V voltage and 0.5 W power ratings. Verify package compatibility for DO-35 axial leads before substitution.
