1N4762A R1G

Single Zener Diodes Overview

The 1N4762AR1G is a single silicon Zener diode manufactured by Taiwan Semiconductor, designed for voltage regulation applications. It features an 82 V nominal reference voltage with a 5% tolerance and operates at a test current of 3 mA. The device dissipates up to 1 W of power and exhibits a maximum dynamic impedance of 200 Ω. It utilizes a DO-204AL (DO-41) axial through-hole package with matte tin-plated leads. The component supports an operating temperature range from -55 °C to +150 °C and complies with RoHS directives.

Single Zener Diodes Feature Summary

• Glass passivated junction construction for enhanced stability
• Built-in strain relief mechanism within the DO-41 package
• Low inductance design suitable for high-frequency switching
• Typical reverse leakage current below 5 μA above 11 V

Single Zener Diodes Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific suffix R1G against official datasheets to confirm packaging details and compliance status. Ensure the ordering code matches the required lead-free and halogen-free specifications. Cross-reference the manufacturer's part number with distributor listings to confirm availability and authenticity before procurement.

Single Zener Diodes Selection Notes

Select this component when an 82 V Zener reference is required in a standard axial package. Consider the 1 W power dissipation limit and 200 Ω dynamic impedance for circuit design. Verify thermal management requirements for operation near the upper temperature limit of 150 °C.

Single Zener Diodes Part Context

This part belongs to the 1N47xxA series of glass-passivated silicon Zener diodes produced by Taiwan Semiconductor. The series covers a wide voltage range using the standardized DO-41 axial leaded package. These components are widely used in general-purpose electronics for stable voltage referencing and protection.

Single Zener Diodes Replacement Considerations

Direct substitutes include Vishay 1N4762A-TR and Microchip 1N4762AUR/TR. Other manufacturers such as STMicroelectronics and onsemi offer equivalent parts within the same series. Verify pinout compatibility and electrical parameter tolerances before substitution.
