SMBG5947BE3/TR13

Single Zener Diodes Overview

The SMBG5947BE3/TR13 is a single Zener diode manufactured by Microsemi Corporation, designed for surface-mount applications. It features an 82 V nominal Zener voltage with a ±5% tolerance and a maximum power dissipation of 2 W. The device utilizes the DO-214AA (SMB) package and is supplied in tape and reel format. It operates within a temperature range of -65°C to +150°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at 82 V with high precision tolerance
• Engineered for surface-mount integration using the SMB package
• Capable of handling 2 W power dissipation under specified conditions

Single Zener Diodes Applications

• Voltage reference circuits requiring 82 V stability
• Overvoltage protection in electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the manufacturer designation as Microsemi Corporation or its successor entity Microchip Technology. Confirm the specific suffix BE3 indicates lead-free compliance and TR13 denotes the tape and reel packaging configuration. Ensure the component matches the DO-214AA physical footprint requirements for your printed circuit board design.

Single Zener Diodes Selection Notes

Select this component when an 82 V Zener voltage is required in a surface-mount SMB package. The 2 W power rating supports moderate current loads. Verify that the operating environment stays within the -65°C to +150°C junction temperature range. Consider the ±5% tolerance if tighter voltage regulation is not critical for the application.

Single Zener Diodes Part Context

This part belongs to the SMBG series of single Zener diodes from Microsemi. The series offers various voltage options in the SMB surface-mount package. The BE3 suffix typically signifies environmental compliance, while TR13 indicates bulk tape and reel shipping. This specific model provides a fixed 82 V regulation point.

Single Zener Diodes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 82 V Zener voltage, 2 W power rating, and DO-214AA package dimensions. Consult official manufacturer substitution guides for verified equivalents.
