1N4762A R1G

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.

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

Applications

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

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.

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.

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.

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.
