SMBJ5941B/TR13

Single Zener Diodes Overview

The SMBJ5941B/TR13 is a surface-mount silicon Zener diode from the SMBJ59 family, manufactured by Microchip Technology. It operates in the DO-214AA (SMB) package with a J-bend design for high-density mounting. The device provides a nominal Zener voltage of 16V with a tolerance of ±5%. It is rated for a maximum DC power dissipation of 2.0W at lead temperatures below 80°C and withstands junction temperatures from -65°C to +150°C. The component features low thermal resistance and complies with RoHS standards.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features a J-bend design in the DO-214AA package for increased PC board mounting density
• Classified as Level 1 moisture sensitivity requiring no dry pack storage
• Capable of withstanding high surge stresses without ESD sensitivity per MIL-STD-750

Single Zener Diodes Applications

• Voltage regulation circuits requiring precise tolerance
• Protection against transient voltage surges
• Reference voltage sources in electronic systems

Single Zener Diodes Procurement Notes

Verify the specific part number suffix TR13 indicates tape and reel packaging configuration. Confirm RoHS compliance status through official datasheets or manufacturer documentation before procurement. Ensure application requirements align with the 2.0W power rating and thermal management constraints specified for the DO-214AA package.

Single Zener Diodes Selection Notes

Select this component when a 16V Zener voltage with ±5% tolerance is required in a surface-mount format. Consider the SMBJ59 family for applications needing higher power ratings compared to standard axial equivalents. Evaluate thermal derating curves if operating conditions exceed ambient limits on FR4 PCBs.

Single Zener Diodes Part Context

This component belongs to the SMBJ59 series of 2.0 Watt Zener diodes, which are equivalent to JEDEC registered 1N5918–1N5924 devices but offer lower thermal resistance. The series covers Zener voltages from 5.1V to 9.1V; however, the SMBJ5941B specifically denotes a 16V variant within the broader SMBJ59 product line context provided by Microchip.

Single Zener Diodes Replacement Considerations

The SMBJ5941B is electrically equivalent to the JEDEC registered 1N5941B axial-lead diode. When replacing, ensure the substitute component matches the 2.0W power rating and DO-214AA package dimensions for proper mechanical fit.
