1N4760AHR1G

Overview

The 1N4760AHR1G is a silicon Zener diode manufactured by Taiwan Semiconductor, 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-204AL (DO-41) axial through-hole package and supports a maximum power dissipation of 1 W. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a Zener impedance of 2000 Ω at a test current of 3.7 mA. It is qualified under AEC-Q101 standards and functions within an operating temperature range of -55 °C to +150 °C.

Feature Summary

• Glass passivated junction construction provides stable performance and protection against mechanical stress.
• AEC-Q101 qualification ensures reliability and suitability for demanding automotive electronic environments.
• Axial leaded DO-41 package design facilitates easy integration into standard through-hole circuit board layouts.

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in automotive electronics
• General-purpose voltage regulation tasks

Procurement Notes

Verify component authenticity and lot traceability directly with Taiwan Semiconductor or authorized distributors before procurement. Confirm that the specific suffix indicates AEC-Q101 automotive qualification status. Ensure compliance with RoHS and REACH directives as specified in the official datasheet. Request full documentation including the certificate of conformity and material declarations to validate regulatory adherence for your specific manufacturing requirements.

Selection Notes

Select this component when a 68 V regulation point is required in high-reliability automotive systems. The DO-41 package suits designs needing robust mechanical mounting via through-hole technology. Verify that the 1 W power rating and 2000 Ω impedance align with the thermal management and signal integrity constraints of the target application circuit.

Part Context

This part belongs to the 1N47xx series of glass-passivated Zener diodes produced by Taiwan Semiconductor. The 'H' prefix typically denotes AEC-Q101 automotive qualification, while 'R1G' specifies reel packaging and halogen-free materials. This series is engineered for general-purpose voltage regulation, offering consistent performance across wide temperature ranges in industrial and automotive sectors.

Replacement Considerations

Cross-reference with other manufacturers' 1N4760A variants, such as those from Vishay or Microchip, ensuring identical 68 V Zener voltage, 1 W power rating, and DO-41 package compatibility. Verify that substitute parts also meet AEC-Q101 automotive reliability standards if required by the original design specifications.
