1N4738 G

Overview

The Microsemi Corporation 1N4738 G is a silicon Zener diode designed for voltage regulation applications. It features a glass encapsulated body with hermetic sealing, housed in the DO-204AL package. The device provides an 8.2V nominal Zener voltage with a tight 1% tolerance and a power dissipation rating of 1W. As a military-grade component, it offers high reliability and extended temperature performance suitable for demanding environments.

Feature Summary

Hermetically sealed glass construction ensures environmental protection
High-reliability design intended for critical applications
Tight voltage tolerance maintains precise regulation

Applications

Military electronic systems requiring strict reliability standards
Aerospace circuits demanding hermetic sealing
High-reliability voltage reference designs

Procurement Notes

Verify that the specific part number includes the 'G' suffix to confirm the hermetically sealed glass variant. Confirm RoHS compliance status as military variants may differ from commercial equivalents. Ensure the supplier provides traceability documentation required for defense or aerospace procurement protocols.

Selection Notes

Select this component when hermetic sealing is mandatory for environmental resistance. Choose this over plastic packages if long-term stability in harsh conditions is required. Verify that the 1W power rating and 8.2V specification align with the circuit requirements before integration.

Part Context

This component belongs to the 1N47xx series of 1-watt Zener diodes manufactured by Microsemi. The 'G' suffix specifically denotes the glass body option, which provides hermetic sealing compared to the plastic 'P' suffix variants. This series covers a wide range of voltages from 3.3V to 100V within the same physical footprint.
