Overview
The Microsemi 1N4731 G is a Zener Voltage Regulator Diode manufactured by Microchip Technology. It belongs to the Zener Diodes product category within the broader Diodes & Rectifiers subcategory. The component is identified by the manufacturer number 1N4731 G and carries the Microchip Technology trademark. According to available specifications, the RoHS compliance status for this specific part variant is listed as Non-Compliant (N). The factory packaging quantity associated with this item is 100 units.
Feature Summary
- Provides voltage regulation functionality as a Zener diode
- Features hermetic-sealed glass encapsulation qualities
- Supports higher rated temperature operation compared to plastic-body variants
Applications
- Voltage regulation in electronic circuits requiring hermetic sealing
- Applications demanding higher rated temperature performance beyond standard plastic packages
- High reliability applications specified by source control drawings
Procurement Notes
Verify current availability directly with the manufacturer or authorized distributors, as stock status may vary. Confirm RoHS compliance requirements against project specifications, as this specific suffix indicates non-compliance. Check for updated ordering requirements and lead times from the supplier before finalizing procurement plans.
Selection Notes
Select this component when hermetic sealing and high-temperature capability are required for voltage regulation. Compare against plastic-body equivalents if environmental sealing is not critical. Ensure the 1W power dissipation rating meets circuit demands. Verify that the non-RoHS status aligns with regulatory constraints of the target application environment.
Part Context
This device is part of the popular 1N4728AG through 1N4764AG series of 1.0 watt Zener diodes produced by Microsemi. These glass body devices offer voltage regulation across a selection range with 5% tolerances. The 'G' suffix specifically denotes the glass encapsulation which provides hermetic-sealed qualities and enhanced thermal ratings compared to the plastic-body 'P' suffix versions of the same JEDEC numbers.
Replacement Considerations
Consider the 1N4731 AGTRE3 for RoHS-compliant alternatives within the same series. Evaluate plastic-body variants like 1N4731 CPTR if hermetic sealing is unnecessary. Surface mount equivalents such as 1N4731 AURE3TR may be suitable for density-constrained designs.
