1N4741A G

Overview

The Microsemi Corporation 1N4741AG is a silicon Zener diode designed for voltage regulation applications. It features an 11V nominal Zener voltage with a 5% tolerance and a maximum power dissipation of 1W. The device utilizes a hermetically sealed glass encapsulation in the DO-204AL (DO-41) axial leaded package. It operates within a temperature range of -65°C to +175°C and is classified as non-RoHS compliant.

Feature Summary

• Hermetically sealed glass body construction
• High rated temperature capability
• Single unidirectional configuration

Applications

• Voltage regulation circuits
• High reliability electronic systems
• Military screening applications

Procurement Notes

Verify compliance requirements before procurement, as this specific part number is not RoHS compliant. Confirm that the hermetic seal and high-temperature rating meet the environmental specifications of the target application. Ensure the DO-204AL package dimensions align with the printed circuit board layout constraints.

Selection Notes

Select this component when hermetic sealing is required for moisture or contamination protection. Choose the 1N4741AG over plastic variants if higher thermal stability or military-grade screening levels are necessary. Verify that the 1W power rating and 11V breakdown voltage match the circuit design parameters.

Part Context

This part belongs to the 1N4728AG through 1N4764AG series of 1.0 watt Zener diodes manufactured by Microsemi. The 'G' suffix specifically denotes the glass encapsulated version, which provides hermetic-sealed qualities and higher rated temperatures compared to the plastic-bodied 'P' suffix options available in the same JEDEC numbering system.

Replacement Considerations

Equivalent parts include other manufacturers' 1N4741A devices in DO-41 packages. For hermetic requirements, verify availability of glass-body equivalents from other suppliers. Plastic versions like 1N4741AP offer similar electrical characteristics but lack hermetic sealing.
