1N4762AG

Single Zener Diodes Overview

The Microsemi Corporation 1N4762AG is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 82V with a tolerance of 5% and a power dissipation rating of 1W. The component utilizes a DO-204AL (DO-41) glass body package, providing hermetic sealing qualities suitable for demanding environments. It operates within a temperature range extending up to 175°C, offering higher rated thermal performance compared to plastic-body variants.

Single Zener Diodes Feature Summary

• Hermetically sealed glass encapsulation provides environmental protection and reliability
• High maximum operating temperature capability exceeding standard plastic packages
• JEDEC registered part number ensuring standardized electrical characteristics

Single Zener Diodes Applications

• Voltage regulation in high-reliability electronic circuits
• Overvoltage protection in aerospace or military systems
• Reference voltage generation in precision instrumentation

Single Zener Diodes Procurement Notes

Verify the specific suffix 'G' confirms the hermetic glass package variant rather than the plastic 'P' version. Confirm RoHS compliance status as the base JEDEC number may have non-compliant manufacturing origins. Ensure the supplier provides traceability documentation required for critical applications involving this microelectronics component.

Single Zener Diodes Selection Notes

Select this component when hermetic sealing and elevated temperature operation are mandatory requirements. Compare against the plastic equivalent if lower thermal resistance is needed instead of hermeticity. Verify that the 82V breakdown voltage aligns with the circuit's regulation needs and that the 1W power rating accommodates the expected current load without derating issues.

Single Zener Diodes Part Context

This device belongs to the popular 1N4728A through 1N4764A series of 1.0-watt Zener diodes manufactured by Microsemi. The series covers a voltage selection from 3.3 to 100 volts. The 'G' suffix specifically denotes the glass body construction, distinguishing it from the plastic molded options available for the same electrical specifications within the broader product family.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4762A components meeting identical JEDEC electrical standards. For hermetic requirements, verify alternative glass-sealed equivalents from qualified suppliers. Plastic replacements like the 1N4762AP offer similar electrical performance but lack the hermetic seal and potentially different thermal limits.
