SMBG5943C/TR13

Single Zener Diodes Overview

The SMBG5943C/TR13 is a surface-mount Zener diode manufactured by Microsemi Corporation. It provides voltage regulation with a nominal Zener voltage of 43 V and a power dissipation rating of 2.0 W. The device features a tight tolerance of ±2%, indicated by the 'C' suffix, and operates within a temperature range of -65°C to +150°C. It utilizes the DO-215AA (SMBG) gull-wing package for visible solder connections and is supplied in reel or cut tape formats.

Single Zener Diodes Feature Summary

• Surface-mount design equivalent to JEDEC registered 1N5943 series
• Higher 2.0 W power rating compared to traditional axial packages
• Low thermal resistance surface mount packaging
• Visible solder connections via gull-wing lead configuration

Single Zener Diodes Applications

• Voltage regulation circuits requiring high-density mounting
• Low-profile electronic assembly applications
• General-purpose Zener voltage reference designs

Single Zener Diodes Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to discontinuation notices. Confirm specific lot dates and RoHS compliance status directly with the manufacturer or certified distributors. Ensure storage conditions meet moisture sensitivity level requirements prior to reflow soldering processes.

Single Zener Diodes Selection Notes

Select this component when a 43 V regulation point with ±2% precision is required in a surface-mount form factor. The SMBG package offers higher power handling than standard axial equivalents. Verify that the PCB footprint supports the DO-215AA gull-wing geometry for proper mechanical stability and thermal performance.

Single Zener Diodes Part Context

This device belongs to the SMBG5913–SMBG5956e3 series of silicon Zener diodes. These components are designed as surface-mount replacements for the JEDEC registered 1N5913 through 1N5956A axial series, offering identical electrical characteristics but with an increased 2.0 W power rating due to improved thermal management in the SMBG package.
