1N4760A R1G

Overview

The 1N4760A R1G is a Zener diode manufactured by Taiwan Semiconductor Corporation, designed for voltage regulation applications. It features a nominal Zener voltage of 68 V with a tolerance of ±5%. The device operates in the DO-41 axial leaded package and supports through-hole mounting. It dissipates up to 1 W of power at ambient temperatures above 25°C. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a Zener impedance of 150 Ω at a test current of 3.7 mA. The component is qualified under AEC-Q101 standards and functions within a temperature range of -55°C to +150°C.

Feature Summary

• Provides stable voltage regulation with a nominal 68 V reference point
• Features low reverse leakage current for efficient standby operation
• Includes built-in strain relief for mechanical durability in axial packages
• Qualified for automotive electronics via AEC-Q101 certification

Applications

• Voltage regulation in automotive electronic systems
• Overvoltage protection circuits
• Reference voltage sources in precision measurement equipment
• Clamping applications in signal processing lines

Procurement Notes

Verify the specific suffix 'R1G' against official Taiwan Semiconductor documentation to confirm reel packaging and RoHS compliance status. Confirm AEC-Q101 qualification requirements with the manufacturer prior to procurement. Ensure the ordering part number matches the exact voltage and package specifications required for the target application design.

Selection Notes

Select this component when a 68 V regulated reference is required in an axial package. Consider the 150 Ω impedance for dynamic load variations. Verify thermal management capabilities for 1 W dissipation. Check compatibility with automated assembly processes due to the axial lead form factor. Ensure the operating temperature range meets the environmental constraints of the final system.

Part Context

This component belongs to the 1N47xx series of high-power Zener diodes produced by Taiwan Semiconductor. These devices are widely used in industrial and automotive sectors for reliable voltage clamping. The 1N4760A variant specifically targets the 68 V segment of the series, offering consistent performance across mass-produced batches while maintaining strict adherence to automotive quality standards.

Replacement Considerations

Cross-reference with other manufacturers' 1N4760A equivalents such as Vishay or Microchip versions. Verify that substitute parts match the 68 V nominal voltage, 1 W power rating, and DO-41 package dimensions. Ensure replacement components also meet AEC-Q101 requirements if automotive qualification is mandatory for the application.
