1N4741ADO41E3

Overview

The Microsemi Corporation 1N4741ADO41E3 is a silicon Zener diode with an 11V nominal breakdown voltage and ±5% tolerance. It operates in the DO-204AL (DO-41) through-hole package, providing 1W power dissipation. The device is RoHS compliant and lead-free. It functions as a unidirectional component with isolated case connection. Operating temperatures range from -65°C to 175°C.

Feature Summary

• Provides stable voltage regulation within a 3.3 to 100-volt selection range
• Features hermetic-sealed glass encapsulation for environmental protection
• Offers higher rated temperature capability compared to plastic-body options

Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage generation

Procurement Notes

Verify that the suffix E3 confirms RoHS compliance and lead-free status. Confirm the DO-204AL package matches design requirements. Ensure the 11V specification aligns with circuit needs. Check for military screening levels if required by application standards.

Selection Notes

Select this part when hermetic sealing and high-temperature operation are necessary. The glass body offers superior thermal performance over plastic alternatives. Consider the 1W power rating for load requirements. Verify compatibility with existing JEDEC form-factor constraints.

Part Context

This component belongs to the 1N4728AG through 1N4764AG series of 1.0-watt Zener diodes. The series provides voltage regulation with standard 5% tolerances. The G suffix indicates hermetic-sealed glass construction. Microsemi manufactures these devices for demanding electronic applications requiring reliability.

Replacement Considerations

Substitutes include other 1N4741 variants with matching DO-41 packages. Ensure replacement parts maintain the 11V breakdown voltage and 1W power rating. Verify hermetic sealing requirements are met by alternative suppliers.
