1N4762AGE3/TR

Overview

The Microchip Technology 1N4762AGE3/TR is a single silicon Zener diode designed for voltage regulation applications. It features an 82V nominal Zener voltage with a tolerance of ±5%. The device is rated for a power dissipation of 1W and operates within a temperature range of -65°C to +175°C. Packaged in the DO-204AL (DO-41) axial leaded format, it utilizes plastic encapsulation. This component serves as a reliable voltage reference or protection element in electronic circuits requiring stable DC voltage levels.

Feature Summary

• Provides precise voltage regulation with a nominal 82V breakdown characteristic
• Capable of handling 1W power dissipation for robust circuit protection
• Engineered for high-temperature operation up to 175°C junction temperature
• Utilizes standard DO-41 axial through-hole packaging for easy integration

Applications

• Voltage reference circuits requiring stable DC levels
• Over-voltage protection in power supply inputs
• Clamping applications in signal conditioning paths
• General-purpose voltage regulation in industrial electronics

Procurement Notes

Verify the specific suffix 'E3' indicates lead-free compliance and 'TR' denotes tape-and-reel packaging configuration. Confirm that the DO-204AL package matches your PCB footprint requirements. Ensure the 82V rating aligns with your circuit's voltage headroom needs. Check for any RoHS directive compliance documentation if required by your manufacturing standards. Validate supplier authenticity for Microchip Technology components.

Selection Notes

Select this component when a stable 82V reference is needed with moderate power handling capabilities. The DO-41 package suits designs requiring axial leads for manual assembly or specific board layouts. Consider the ±5% tolerance for precision requirements. Evaluate thermal management needs given the 1W dissipation rating. Compare against other Zener voltages if system requirements differ from 82V.

Part Context

This part belongs to the 1N47xx series of Zener diodes, widely used for voltage regulation. Microchip Technology manufactures these devices using silicon planar technology. The 1N4762 variant specifically targets the 82V breakdown region. The E3 suffix typically signifies environmental compliance, while TR indicates reel packaging for automated placement.

Replacement Considerations

Direct substitutes include the 1N4762AUR/TR and 1N4762AGE3 from Microchip. Other manufacturers offer equivalent 82V 1W Zener diodes in DO-41 packages, such as those from Taiwan Semiconductor. Verify pinout compatibility and thermal characteristics before substitution.
