Overview
The Microchip Technology 1N4762AGE3 is a hermetically sealed silicon Zener diode designed for voltage regulation applications. It features a glass encapsulated DO-41 (DO-204AL) axial package and operates within an extended temperature range from -65°C to +175°C. The device provides a nominal Zener voltage of 82V with a 10% tolerance at a test current of 5mA, dissipating up to 1W of power. This component offers high reliability suitable for demanding environments requiring stable voltage reference performance.
Feature Summary
- Hermetically sealed glass encapsulation ensures environmental protection and long-term stability
- Extended operating temperature range supports operation in extreme thermal conditions
- High power dissipation capability allows effective voltage regulation under significant load
Applications
- Precision voltage reference circuits
- Overvoltage protection systems
- Temperature compensated regulator designs
Procurement Notes
Verify the specific suffix 'AG' confirms hermetic sealing requirements against standard plastic variants. Confirm RoHS compliance status via the 'e3' designation if lead-free assembly is mandatory. Cross-reference datasheet electrical characteristics to ensure compatibility with circuit design parameters before procurement.
Selection Notes
Select this component when hermetic sealing is required for harsh environment reliability. Ensure the 82V breakdown voltage aligns with system regulation needs. Verify that the axial DO-41 package fits the available PCB real estate and mounting constraints compared to surface mount alternatives.
Part Context
This part belongs to the 1N47xx series of 1-watt Zener diodes manufactured by Microchip Technology. The 'A' indicates tighter tolerance specifications, while 'G' denotes hermetic sealing. The 'e3' suffix signifies lead-free termination finish compliant with modern environmental standards.
Replacement Considerations
Equivalent parts include the MSP1N4762G from Microsemi which shares identical hermetic and electrical specifications. Standard non-hermetic equivalents like the 1N4762A lack the sealed glass construction required for extreme durability.
