1N5231C-TR

Single Zener Diodes Overview

The Vishay General Semiconductor - Diodes Division 1N5231C-TR is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial leaded package. It features a nominal Zener voltage of 5.1 V with a tight ±2 % tolerance, as indicated by the 'C' suffix. The device operates at a test current of 20 mA and dissipates up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 2 V and a dynamic resistance of 17 Ω at the test current.

Single Zener Diodes Feature Summary

• Provides precise voltage stabilization with a tight ±2 % Zener voltage tolerance
• Utilizes a standard DO-35 axial leaded package for through-hole mounting
• Features a low forward voltage drop of 1.1 V at 200 mA

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the 'C' suffix to ensure the required ±2 % tolerance specification is met. Confirm the '-TR' suffix indicates the taped and reeled packaging format. Cross-reference the specific document revision against the manufacturer's official datasheet to validate all electrical parameters before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a stable reference voltage near 5.1 V is required with high precision. The ±2 % tolerance makes it suitable for applications demanding tighter voltage regulation than standard ±5 % devices. Ensure the circuit design accommodates the 500 mW power dissipation limit and the specified thermal resistance requirements for the chosen operating environment.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide range of nominal voltages from 2.4 V to 75 V. The 1N5231 variant specifically targets the 5.1 V segment, offering a balance between low leakage and manageable dynamic impedance for general-purpose electronic designs.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same Vishay series include 1N5231B-TR, which offers a wider ±5 % tolerance. Other manufacturers producing standard DO-35 packaged Zener diodes with a 5.1 V nominal rating may serve as functional substitutes if pinout and electrical tolerances align with the application requirements.
