1N4759AHR1G

Overview

The 1N4759AHR1G is a single silicon Zener diode manufactured by Taiwan Semiconductor, designed for through-hole mounting in the DO-41 (DO-204AL) axial leaded package. It features a nominal Zener voltage of 62 V with a tolerance of ±5%. The device supports a power dissipation of 1 W and operates within a temperature range of -55°C to +150°C. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a Zener impedance of 2000 Ω at a test current of 4 mA. This component holds AEC-Q101 qualification for automotive reliability standards.

Feature Summary

• AEC-Q101 qualified for automotive-grade reliability requirements
• Hermetically sealed glass construction with oxide passivated die
• Double slug type metallurgically bonded design for thermal stability

Applications

• Voltage regulation in automotive electronic circuits
• Overvoltage protection for sensitive semiconductor components
• Reference voltage generation in precision measurement systems

Procurement Notes

Verify the specific suffix HR1G against the manufacturer's latest datasheet to confirm packaging configuration and compliance status. Confirm AEC-Q101 certification validity directly with Taiwan Semiconductor or authorized distributors. Ensure the DO-41 package dimensions match the target PCB footprint before finalizing procurement decisions.

Selection Notes

Select this component when a stable 62 V reference is required in high-reliability environments. The AEC-Q101 qualification makes it suitable for automotive applications where strict quality standards apply. Consider the 1 W power rating and DO-41 package size for thermal management and space constraints in the final assembly design.

Part Context

This part belongs to the 1N47xxA series of 1-watt Zener diodes produced by Taiwan Semiconductor. The series offers a wide range of voltage options from 3.3 V to 100 V. The 'A' suffix typically denotes a tighter ±5% voltage tolerance compared to standard variants. The HR1G suffix indicates specific reel packaging and manufacturing lot details defined by the manufacturer.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4759A equivalents in the DO-41 package. Verify that substitute parts meet the same 62 V nominal voltage, 1 W power rating, and AEC-Q101 automotive qualification if required for the application.
