1N4763A R1G

Overview

The 1N4763A R1G is a silicon Zener diode manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 82 V with a maximum tolerance of 5%. The device is designed for a maximum power dissipation of 1 W and operates within a junction temperature range up to 150 °C. Packaged in the DO-204AL (DO-41) axial leaded format, it utilizes matte tin-plated leads for solderability. The component incorporates a glass-passivated chip junction and includes built-in strain relief to enhance mechanical stability.

Feature Summary

• Glass passivated junction construction for reliable operation
• Built-in strain relief mechanism for mechanical durability
• Low leakage current characteristics typical above 11 V
• Halogen-free molding compound compliant with environmental directives

Applications

• Voltage regulation circuits requiring stable reference levels
• Protection against overvoltage transients in electronic systems
• Clamping applications in signal processing paths

Procurement Notes

Verify the specific suffix 'R1G' against official Taiwan Semiconductor documentation to confirm packing code details and RoHS compliance status. Ensure the ordering part number matches the required package style and terminal finish specifications for your assembly process.

Selection Notes

Select this component when a standard 82 V Zener reference is needed in an axial through-hole package. Consider the 1 W power rating and 150 °C thermal limit for your thermal management design. Verify that the 5% voltage tolerance meets the precision requirements of your circuit application.

Part Context

This device belongs to the standard 1N47xx series of power Zener diodes. It serves as a unidirectional voltage regulator element. The DO-204AL package provides a robust solution for general-purpose discrete semiconductor applications where axial mounting is preferred.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4763A equivalents in DO-41 packages. Ensure replacement parts match the 82 V nominal voltage, 1 W power rating, and 5% tolerance specifications.
