SMBG4732E3/TR13

Single Zener Diodes Overview

The SMBG4732E3/TR13 is a single-element silicon Zener diode manufactured by Microsemi Corporation. It features a nominal Zener voltage of 4.7V with a tolerance of 10%. The device is designed for surface-mount applications in the DO-215AA (SMBG) plastic package, providing a maximum power dissipation of 1.25W. It operates within a temperature range of -65°C to +150°C and complies with RoHS standards.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using unidirectional silicon junction technology
• Utilizes a plastic encapsulated SMBG package for visible solder connections
• Complies with environmental directives including lead-free specifications

Single Zener Diodes Applications

• Voltage regulation circuits
• Overvoltage protection systems
• General-purpose electronic equipment

Single Zener Diodes Procurement Notes

Verify the exact part number against official Microsemi documentation, as suffixes such as 'TR13' indicate specific reel packaging configurations. Confirm RoHS compliance status and ensure the component meets the required thermal and electrical specifications for the intended application environment before procurement.

Single Zener Diodes Selection Notes

Select this component when a 4.7V reference or regulation point is required in a surface-mount design. The SMBG package offers higher power handling than standard axial equivalents. Ensure the circuit design accommodates the 10% voltage tolerance and that the operating temperature remains within the specified industrial limits.

Single Zener Diodes Part Context

This component belongs to the SMBG series of surface mount Zener diodes from Microsemi. These devices are JEDEC registered and serve as surface-mount replacements for traditional 1N47xx axial Zener diodes, offering comparable electrical characteristics in a compact form factor suitable for high-density PCB layouts.

Single Zener Diodes Replacement Considerations

Direct substitutes include other SMBG4732 variants with different tolerances or packaging suffixes, provided they meet the 4.7V and 1.25W requirements. Cross-reference with Microsemi's current product lifecycle notices to ensure availability.
