1N5231D/TR

Single Zener Diodes Overview

The Microchip Technology 1N5231D/TR is a single Zener diode with a nominal voltage of 5.1 V and a maximum power dissipation of 500 mW. It features a maximum dynamic impedance of 17 ohms and a test current of 20 mA. The device supports through-hole mounting in the DO-204AH (DO-35) package, operates within a temperature range of -65 °C to +200 °C, and has a maximum reverse leakage current of 5 µA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 5.1 V reference level
• Designed for high-temperature operation up to 200 °C
• Utilizes a standard through-hole axial leaded package

Single Zener Diodes Applications

• General-purpose voltage regulation circuits
• Reference voltage sources in electronic systems
• Over-voltage protection applications

Single Zener Diodes Procurement Notes

Verify the specific tolerance grade upon procurement, as datasheets indicate variations such as ±1% or ±5%. Confirm the manufacturer source, as Philips/NXP also produced this part number. Ensure the reel packaging matches the required quantity per tape specification for automated assembly processes.

Single Zener Diodes Selection Notes

Select this component when a 5.1 V Zener reference is required in a DO-35 through-hole package. Consider the 500 mW power rating and 17 Ω impedance for low-current regulation tasks. Verify compatibility with operating temperatures up to 200 °C if used in high-heat environments.

Single Zener Diodes Part Context

This part belongs to the standard 1N52xx series of Zener diodes, widely used for basic voltage clamping and regulation. The 'D' suffix typically denotes the DO-35 glass axial package, while '/TR' indicates tape and reel packaging for surface mount or automated through-hole insertion equipment.

Single Zener Diodes Replacement Considerations

Public confirmed substitutes include 1N5231B-1/TR and 1N5231CTR from other manufacturers offering equivalent electrical characteristics.
