1N4763AG

Overview

The 1N4763AG is a silicon unidirectional Zener diode manufactured by Microsemi Corporation. It features a nominal Zener voltage of 91V with a tolerance of 5% and a maximum power dissipation of 1W. The device utilizes a DO-204AL (DO-41) glass axial leaded package that is hermetically sealed. It supports a maximum operating temperature of 175°C and includes two isolated terminals.

Feature Summary

• Hermetically sealed glass encapsulation for environmental protection
• High thermal stability suitable for elevated temperature environments
• JEDEC registered standard voltage regulation

Applications

• Voltage regulation in high-reliability circuits
• Overvoltage protection systems
• Reference voltage generation in aerospace applications

Procurement Notes

Verify the specific suffix 'G' to confirm the hermetic glass package variant, as non-hermetic plastic options exist within the same series. Confirm RoHS compliance status if required, as this specific part number may not meet current environmental directives. Ensure the supplier provides traceability documentation consistent with Microsemi's manufacturing standards.

Selection Notes

Select this component when hermetic sealing and high-temperature operation are mandatory requirements. The glass body offers superior thermal resistance compared to plastic alternatives but requires careful handling during assembly. Verify that the 91V breakdown voltage aligns with the circuit design specifications before integration.

Part Context

This component belongs to the 1N4728A through 1N4764A series of 1-watt Zener diodes produced by Microsemi's Scottsdale Division. The series covers a wide voltage range from 3.3V to 100V. The 'G' suffix specifically denotes the glass-body construction, distinguishing it from the plastic-bodied 'P' suffix variants available in the same JEDEC numbering system.

Replacement Considerations
