Overview
The Microsemi Corporation 1N4764 G is a silicon planar Zener diode housed in a hermetically sealed glass DO-41 package. It provides voltage regulation with a nominal Zener voltage of 100V and a power dissipation rating of 1W. The device features a standard tolerance of 10% and operates within a junction temperature range of -65°C to +200°C. This component belongs to the JEDEC registered 1N4728 through 1N4764 series, designed for applications requiring reliable voltage reference or protection in harsh environments.
Feature Summary
- Hermetically sealed glass encapsulation ensures environmental stability
- Silicon planar construction for consistent electrical performance
- High thermal resistance capability suitable for elevated temperatures
Applications
- Voltage regulation circuits
- Overvoltage protection systems
- Precision voltage references
Procurement Notes
Verify the specific suffix 'G' indicates the glass body variant when sourcing replacements. Confirm RoHS compliance status as historical Microsemi data may vary by production batch. Ensure the supplier provides traceability documentation for hermetic sealing integrity. Cross-reference the manufacturer's current datasheet for any updates to mechanical dimensions or maximum ratings before finalizing procurement specifications.
Selection Notes
Select this component when a hermetically sealed package is required for high-reliability applications. The glass DO-41 package offers superior thermal performance compared to plastic equivalents. Consider the 100V breakdown voltage and 1W power rating against circuit requirements. Evaluate the operating temperature range to ensure compatibility with the intended environment.
Part Context
This part is part of the widely used 1N47xx series of 1-watt Zener diodes. The 'G' suffix specifically denotes the glass-body option, which provides hermetic sealing and higher temperature ratings compared to the plastic-bodied variants. It serves as a direct equivalent to other manufacturers' 1N4764 devices within the same JEDEC specification framework.
Replacement Considerations
Equivalent parts include the MSP1N4764PE3 (plastic body) and SMBG4764C-TR13 (surface mount). Verify that replacement packages match the physical footprint and lead configuration of the original design.
