1N4734 G

Single Zener Diodes Overview

The Microsemi 1N4734 G is a hermetically sealed glass body Zener diode with a nominal voltage of 5.6 V and a power dissipation rating of 1 W. It features a DO-204AL package and provides voltage regulation within a selection from 3.3 to 100 volts. The device offers tighter tolerances compared to standard plastic variants, ensuring stable performance in demanding environments.

Single Zener Diodes Feature Summary

• Hermetically sealed glass compression bonded construction for high reliability
• Corrosion-resistant external surfaces with readily solderable terminals
• Higher rated temperature capability compared to plastic-body equivalents

Single Zener Diodes Applications

• Voltage regulation in high-reliability applications
• Circuits requiring hermetic sealing qualities
• Temperature-sensitive electronic systems

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements against the current datasheet to ensure compatibility with your design specifications. Confirm RoHS compliance status as it varies by manufacturing batch and region. Check for any military screening prefixes if your application demands MIL-PRF-19500 standards. Ensure the supplier provides valid traceability documentation for the hermetic seal integrity.

Single Zener Diodes Selection Notes

Select this component when hermetic sealing is mandatory for environmental protection or long-term stability. Compare thermal resistance values against plastic alternatives to determine suitability for heat-dissipating designs. Verify that the 1 W power rating aligns with the expected operating conditions and derating factors required by your system architecture.

Single Zener Diodes Part Context

This part belongs to the 1N4728AG through 1N4764AG series of 1.0 watt Zener diodes manufactured by Microsemi. The series provides extensive voltage selection with various tolerance options identified by different suffix letters. The 'G' suffix specifically denotes the glass encapsulation option which offers superior hermetic qualities over the plastic 'P' suffix variants.

Single Zener Diodes Replacement Considerations

Equivalent surface mount versions are available in the SMAJ and MLL series. Plastic body equivalents exist under the same JEDEC numbering but lack hermetic sealing. Consult factory documentation for specific military screening prefixes such as MQ, MX, MV, or MSP if enhanced screening levels are required.
