1N4709/TR

Single Zener Diodes Overview

The Microchip Technology 1N4709/TR is a single silicon Zener diode rated at 24V nominal voltage with a 5% tolerance. It features a maximum power dissipation of 500mW and operates within a temperature range of -65°C to +175°C. The component utilizes a DO-35 axial through-hole package, measuring approximately 5.08mm in length and 2.29mm in diameter. Key electrical characteristics include a maximum reverse leakage current of 50nA and a test current of 50µA.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction for environmental stability
• Wide operating temperature range suitable for harsh conditions
• Standard ±5% voltage tolerance for precision regulation

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection in sensitive electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific suffix (TR) indicates reel packaging when sourcing. Confirm manufacturer documentation aligns with Microchip Technology specifications rather than generic equivalents. Ensure the DO-35 package dimensions match board layout requirements. Check for RoHS compliance status if required by project standards. Validate that the 500mW power rating suffices for the intended thermal environment.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 24V Zener reference in an axial package. Consider the 500mW dissipation limit against expected surge currents. The wide temperature range supports industrial or automotive environments. Compare leakage current specifications against other series if low standby power is critical. Ensure the through-hole mounting style fits the assembly process.

Single Zener Diodes Part Context

This part belongs to the standard 1N47xx series of 500mW Zener diodes. These components are widely used for basic voltage regulation tasks. The DO-35 package is a legacy form factor still prevalent in through-hole designs. Microchip Technology continues production of these established parts for compatibility with existing schematics.

Single Zener Diodes Replacement Considerations

Cross-reference with 1N4709 from other manufacturers like Central Semiconductor or General Semiconductor. Verify identical 24V rating and 500mW power handling before substitution. Ensure package compatibility between DO-35 and DO-204AH variants if space permits.
