1N4702C/TR

Overview

The Microchip Technology 1N4702C/TR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 15 V with a tight tolerance of ±2%. The device is rated for a power dissipation of 500 mW and operates within an extended temperature range from -65°C to 175°C. Packaged in the DO-7 through-hole format, it exhibits a maximum forward voltage of 1.1 V and a leakage current of 50 nA.

Feature Summary

• Provides stable voltage regulation with high precision tolerance
• Capable of operation in extreme thermal environments
• Utilizes standard through-hole mounting for easy integration

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in sensitive electronic systems
• Clamping applications in signal processing paths

Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging configuration when ordering. Confirm RoHS compliance status as some variants may be non-RoHS. Ensure the DO-7 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 15 V regulation point is required with strict tolerance limits. Consider the 500 mW power rating against expected surge currents. Evaluate the extended temperature range suitability for harsh operating conditions compared to standard commercial grade alternatives.

Part Context

This part belongs to the 1N47xx series of axial leaded Zener diodes manufactured by Microchip Technology. These components are widely used in general-purpose electronics for basic voltage stabilization tasks. The 1N4702C variant specifically targets applications needing higher accuracy than standard industrial grades.

Replacement Considerations

Compatible substitutes include other 15 V Zener diodes with ±2% tolerance and 500 mW rating in DO-7 packages. Verify pinout compatibility and thermal characteristics before substitution.
