1N4762 G

Overview

The Microsemi Corporation 1N4762 G is a silicon Zener diode designed for voltage regulation applications. It features an 82V nominal Zener voltage with a 10% tolerance and a maximum power dissipation of 1W. The device utilizes a DO-204AL (DO-41) glass encapsulated package, providing hermetic sealing suitable for demanding environments. It operates within a temperature range of -65°C to 175°C and contains two isolated terminals.

Feature Summary

• Hermetically sealed glass body construction
• High thermal stability for elevated temperatures
• Single unidirectional configuration

Applications

• Voltage regulation in harsh environments
• Overvoltage protection circuits
• Reference voltage generation

Procurement Notes

Verify the specific suffix 'G' confirms the hermetic glass package variant rather than plastic alternatives. Confirm lead-free status requirements as standard versions may not be RoHS compliant. Ensure the manufacturer designation aligns with current Microchip Technology ownership following the acquisition of Microsemi assets.

Selection Notes

Select this component when hermetic sealing is mandatory for environmental resistance. Compare against plastic variants if lower thermal resistance or cost efficiency is prioritized over moisture barrier integrity. Verify that the 1W power rating and 82V breakdown voltage match the circuit design constraints.

Part Context

This part belongs to the 1N47xx series of 1-watt Zener diodes manufactured by Microsemi. The 'G' suffix specifically denotes the glass-encapsulated, hermetically sealed version, distinguishing it from the plastic-bodied 'P' suffix counterparts within the same JEDEC numbering system.
