SMBG4741A/TR13

Single Zener Diodes Overview

The SMBG4741A/TR13 is a single Zener diode manufactured by Microsemi Corporation, designed for surface-mount applications in the SMBG (DO-215AA) package. It features a nominal Zener voltage of 11 V with a tolerance of ±5% and a maximum power dissipation of 2 W. The device operates within a temperature range of -65°C to +150°C and exhibits a maximum reverse leakage current of 5 µA at 8.4 V. This component is currently classified as obsolete.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with a nominal 11 V Zener potential
• Supports high thermal operation up to 150°C junction temperature
• Utilizes a compact SMBG surface-mount plastic encapsulation

Single Zener Diodes Applications

• Voltage reference circuits requiring 11 V stability
• Overvoltage protection in surface-mount assemblies
• Clamping applications in electronic signal paths

Single Zener Diodes Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Verification of availability should focus on surplus distributors or secondary markets rather than direct manufacturing channels. Confirm RoHS compliance status carefully, as some sources indicate lead-containing variants exist alongside compliant versions. Ensure the specific suffix matches the required environmental standard before procurement.

Single Zener Diodes Selection Notes

Select this part only if the 11 V Zener voltage and 2 W power rating align precisely with circuit requirements. The SMBG package dictates specific footprint constraints for PCB layout. Designers must account for the ±5% voltage tolerance in precision applications. Verify that the operating temperature range meets the environmental conditions of the final assembly.

Single Zener Diodes Part Context

The SMBG series represents a line of surface-mount Zener diodes offering higher power handling compared to smaller packages like SMA. Manufactured by Microsemi, these components are intended for robust voltage regulation tasks. The TR13 suffix typically denotes reel packaging for automated insertion processes.

Single Zener Diodes Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the obsolete status of the SMBG4741A/TR13.
