1N4759A R1G

Overview

The 1N4759A R1G is a single silicon Zener diode manufactured by Taiwan Semiconductor, designed for voltage regulation applications. It features a nominal Zener voltage of 62 V with a tolerance of ±5%. The device is housed in the DO-41 (DO-204AL) axial leaded package and supports through-hole mounting. It dissipates up to 1 W of power at ambient temperature. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a Zener impedance of 125 Ω measured at a test current of 4 mA. It operates within a temperature range of -65 °C to +200 °C.

Feature Summary

• Provides stable voltage regulation using a glass-passivated junction design
• Features built-in strain relief for mechanical robustness
• Supports high-temperature soldering processes

Applications

• General-purpose voltage regulation circuits
• Overvoltage protection stages
• Reference voltage generation in power supplies

Procurement Notes

Verify the specific suffix 'R1G' against the manufacturer's official datasheet to confirm packaging details and compliance status. Ensure the component matches the required voltage and power specifications for the target application before procurement.

Selection Notes

Select this component when a 62 V regulation point is required in a standard through-hole assembly. Consider the 1 W power rating and operating temperature limits to ensure thermal management meets circuit requirements.

Part Context

This part belongs to the 1N47xx series of 1 Watt Zener diodes. These components are widely used in industrial and commercial electronics for basic voltage clamping and regulation tasks requiring reliable performance in standard axial packages.

Replacement Considerations

Compatible replacements include other manufacturers' 1N4759A variants such as those from onsemi or Central Semiconductor, provided they meet the same 62 V, 1 W, and DO-41 package specifications.
