1N4742 G

Overview

The Microsemi Corporation 1N4742 G is a Zener Voltage Regulator Diode. It is classified under the product category of Zener Diodes and manufactured by Microchip Technology, formerly Microsemi. The component is identified as non-compliant with RoHS standards. According to distributor records, this specific part number is currently listed as obsolete or discontinued.

Part Context

This component belongs to the standard 1N47xx series of silicon Zener diodes. While the broader family includes active surface mount and plastic axial variants, the 1N4742 G specifically denotes a glass-encapsulated version within the legacy product line. It serves as a voltage reference element in electronic circuits requiring stable regulation at its nominal breakdown voltage.

Replacement Considerations

The 1N4742 G is officially listed as obsolete. Designers must consult current Microchip Technology catalogs for active equivalents. Replacement strategies should focus on verifying electrical compatibility with modern surface-mount or leaded alternatives that maintain the required voltage tolerance and power dissipation characteristics.
