1N4759AG/TR

Overview

The Microchip Technology 1N4759AG/TR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 62 V with a tolerance of ±5%. The device operates in the DO-41 axial through-hole package and dissipates up to 1 W of power. Key electrical characteristics include a maximum reverse leakage current of 5 µA, a Zener impedance of 125 Ohms, and a test current of 4 mA. It supports a forward current of 200 mA and functions within a temperature range of -65 °C to +200 °C.

Feature Summary

• Provides stable voltage regulation at 62 V with tight manufacturing tolerances.
• Constructed with hermetically sealed glass encapsulation for environmental protection.
• Capable of handling high thermal loads with an extended maximum operating temperature.

Applications

• Precision voltage reference circuits
• Overvoltage protection stages
• Power supply regulation modules

Procurement Notes

Verify the specific suffix AG/TR against official Microchip documentation to confirm lead-free compliance and reel packaging specifications. Ensure the DO-41 footprint matches the target PCB design. Cross-reference the 5 µA leakage limit with system requirements to prevent performance degradation in low-current applications.

Selection Notes

Select this component when a robust 62 V regulation point is required in high-temperature environments. The DO-41 package offers reliable through-hole mounting for industrial equipment. Consider the 125 Ohm impedance for noise-sensitive designs where lower ripple is critical compared to higher impedance alternatives.

Part Context

This part belongs to the standard 1N47xx series of one-watt Zener diodes manufactured by Microchip Technology. It utilizes a silicon junction within a glass passivated DO-41 case. The series is widely recognized for its consistency in voltage regulation across various industrial and commercial electronic systems.

Replacement Considerations

Compatible substitutes include the 1N4759A from onsemi or the 1N4759ARL from NXP/Motorola. Verify that replacement parts maintain the same 62 V rating, 1 W power dissipation, and DO-41 mechanical dimensions to ensure direct interchangeability.
