1N4763 G

Overview

The Microsemi Corporation 1N4763 G is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 91 V with a tolerance of 5%. The device is rated for a maximum power dissipation of 1 W and operates within a temperature range extending up to 175 °C. It utilizes a DO-204AL glass body package, providing hermetic sealing suitable for demanding environments.

Feature Summary

• Hermetically sealed glass encapsulation ensures environmental protection
• High thermal stability supports elevated operating temperatures
• JEDEC registered part number for standardized compatibility

Applications

• Voltage regulation in harsh environments
• Reference voltage sources requiring high reliability
• Overvoltage protection circuits

Procurement Notes

Verify the specific manufacturer source, as production rights for this JEDEC number may reside with entities such as Microchip Technology following industry acquisitions. Confirm that the 'G' suffix denotes the required hermetic glass package variant rather than the plastic equivalent. Ensure compliance with lead-based material specifications if RoHS exemption is necessary for the application.

Selection Notes

Select this component when hermetic sealing and high-temperature operation are critical requirements. The glass body construction offers superior thermal resistance compared to plastic alternatives. Verify that the 91 V breakdown voltage aligns with circuit design needs and that the 1 W power rating accommodates expected current loads without exceeding thermal limits.

Part Context

This component belongs to the 1N4728A through 1N4764A series of 1-watt Zener diodes. The series provides extensive voltage selection from 3.3 to 100 volts. The 'G' suffix specifically identifies the glass-body version, which is distinct from the plastic-bodied 'P' suffix variants available within the same JEDEC numbering system.
