1N4734AGE3/TR

Overview

The Microchip Technology 1N4734AGE3/TR is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 5.6 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W and operates within an extended temperature range from -65 °C to +175 °C. Packaged in the DO-204AL (DO-41) axial leaded format, it utilizes a glass encapsulation. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 2 V and a dynamic impedance of 5 Ω at the test current of 45 mA.

Feature Summary

• Provides stable voltage regulation using a single unidirectional silicon junction.
• Engineered for high thermal stability across a wide operating temperature range.
• Utilizes a robust glass encapsulated axial package for reliable through-hole mounting.

Applications

• Voltage reference circuits requiring precise potential levels.
• Overvoltage protection stages in electronic systems.
• General-purpose voltage regulation tasks.

Procurement Notes

Verify the specific suffix 'G' indicates glass encapsulation and 'E3' denotes lead-free compliance against the official datasheet. Confirm the 'TR' suffix corresponds to the required reel packaging quantity. Ensure the manufacturer designation matches Microchip Technology specifications before finalizing procurement orders.

Selection Notes

Select this component when a 5.6 V regulation point is required with a 1 W power rating. The DO-41 package suits through-hole designs. Verify that the 5 Ω dynamic impedance meets circuit sensitivity requirements. Ensure the operating environment stays within the specified -65 °C to +175 °C limits.

Part Context

This part belongs to the standard 1N47xx series of 1-watt Zener diodes manufactured by Microchip Technology. The series offers various voltage options within the same physical form factor. The 1N4734 variant specifically targets the 5.6 V segment of this lineup, providing a common reference voltage for analog and digital circuit designs.

Replacement Considerations

Cross-reference with other manufacturers offering the 1N4734 specification in DO-41 glass packages. Verify identical pinout, voltage tolerance, and power dissipation ratings. Ensure any substitute maintains the same thermal resistance and leakage current characteristics.
