SMBG4744C/TR13

Single Zener Diodes Overview

The SMBG4744C/TR13 is a surface mount silicon Zener diode manufactured by Microsemi Corporation. It operates within the SMBJ/SMBG series, providing voltage regulation in a DO-214AA (SMB) package. The device features a nominal Zener voltage of 15 V with a tolerance of ±2%, indicated by the 'C' suffix. It is rated for a maximum power dissipation of 2.0 W and includes an e3 suffix denoting lead-free composition compliant with RoHS standards.

Single Zener Diodes Feature Summary

• Surface mount design equivalent to JEDEC registered 1N4744A
• Low thermal resistance for efficient heat dissipation
• Lead-free construction compliant with environmental directives

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Protection against voltage transients

Single Zener Diodes Procurement Notes

Verify the specific manufacturer documentation for the SMBG4744C/TR13 to confirm current production status and electrical parameters. Ensure the component matches the required voltage tolerance and package type for the intended application. Cross-reference with official Microchip or Microsemi datasheets for accurate specifications before procurement.

Single Zener Diodes Selection Notes

Select this component when a 15 V Zener diode with high precision is required in a surface mount configuration. The 2.0 W power rating allows for higher energy handling compared to standard 1.0 W axial equivalents. Consider the DO-214AA footprint constraints and the need for lead-free compliance in the final assembly process.

Single Zener Diodes Part Context

This part belongs to the SMBJ/SMBG series of 2.0 Watt Zener diodes offered by Microsemi. These devices are designed as surface mount equivalents to the traditional 1N47xx series, offering identical electrical characteristics but with improved mounting density and thermal performance due to the SMB package geometry.

Single Zener Diodes Replacement Considerations

The SMBG4744C/TR13 is electrically equivalent to the 1N4744A Zener diode. Other manufacturers producing 15 V, 2 W Zener diodes in the DO-214AA package may serve as functional substitutes if pinout and thermal characteristics align.
