1N4741AGE3/TR

Overview

The 1N4741AGE3/TR is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features an 11 V nominal Zener voltage with a ±5% tolerance and operates in the DO-204AL (DO-41) axial through-hole package. The device supports a maximum power dissipation of 1 W and withstands a forward current of 200 mA. Electrical characteristics include a maximum reverse leakage current of 1 µA, a Zener impedance of 22 Ohms at a test current of 12.5 mA, and a forward voltage drop of 1.2 V. It functions reliably within an operating temperature range from -65°C to +175°C.

Feature Summary

• Provides stable voltage regulation using Zener breakdown characteristics
• Capable of withstanding high thermal stress for harsh environment operation
• Utilizes axial leaded construction for reliable through-hole mounting

Applications

• Harsh environment automotive under-hood systems
• Industrial power supply circuits
• General purpose voltage regulation tasks

Procurement Notes

Verify compliance with RoHS directives before integration. Confirm that the reel packaging format aligns with automated assembly requirements. Ensure the specified voltage tolerance meets circuit design constraints. Check for any specific environmental certifications required by the target application standards.

Selection Notes

Select this component when an 11 V reference is required in a standard axial package. Consider the 1 W power rating for thermal management needs. Evaluate the wide temperature range suitability against ambient conditions. Compare the Zener impedance specifications with other available regulators for precision requirements.

Part Context

This part belongs to the 1N474x series of Zener diodes produced by Microchip Technology. These components are widely used for basic voltage clamping and regulation. The 'E3' suffix indicates lead-free composition, while '/TR' denotes tape and reel packaging for efficient surface mount or automated insertion processing.

Replacement Considerations

Compatible substitutes include the 1N4741AG and 1N4741A variants. Verify that alternative parts maintain the same 11 V Zener voltage and 1 W power dissipation rating. Ensure the replacement package matches the DO-41 form factor for mechanical compatibility.
