1N4760 G

Overview

The Microsemi Corporation 1N4760 G is a silicon planar Zener diode housed in a hermetically sealed glass DO-204AL (DO-41) package. It provides voltage regulation with a nominal Zener voltage of 68V and a power dissipation rating of 1W. The device features a standard tolerance of ±5% and supports an operating temperature range up to 175°C, making it suitable for high-reliability applications requiring robust environmental sealing.

Feature Summary

• Hermetically sealed glass encapsulation ensures protection against moisture and contaminants
• High thermal stability rated for elevated operating temperatures
• JEDEC registered part number ensuring standardized electrical characteristics

Applications

• Voltage regulation in military-grade electronic systems
• Power supply circuits requiring high reliability
• Protection stages in aerospace instrumentation

Procurement Notes

Verify the specific suffix 'G' confirms the hermetic glass construction distinct from plastic variants. Confirm RoHS compliance status as older manufacturing runs may be lead-based. Check current availability as this component type may have limited stock or obsolescence notices from the manufacturer.

Selection Notes

Select this variant when hermetic sealing is mandatory for environmental durability. Compare thermal resistance values against plastic equivalents if heat dissipation is critical. Ensure the 68V breakdown voltage aligns precisely with the circuit's reference requirements without excessive derating.

Part Context

This component belongs to the 1N47xx series of 1-watt Zener diodes manufactured by Microsemi. The series offers a wide voltage range from 3.3V to 100V. The 'G' suffix specifically denotes the glass body construction, differentiating it from the 'P' suffix plastic versions which offer lower thermal resistance but lack hermetic sealing.

Replacement Considerations

Equivalent parts include MV1N4760GTR and 1N4760CG from Microsemi/Microchip. Cross-reference with Vishay or Taitron 1N4760A-T variants only if non-hermetic packaging is acceptable.
