SMAJ5951AE3/TR13

Single Zener Diodes Overview

The SMAJ5951AE3/TR13 is a single Zener diode manufactured by Microsemi Corporation. It features a nominal Zener voltage of 120 V with a tolerance of ±10%. The device is rated for a maximum power dissipation of 3 W and utilizes the DO-214AC (SMAJ) surface-mount package. It operates within a junction temperature range of -65 °C to +150 °C.

Single Zener Diodes Feature Summary

• Provides voltage regulation in the 3.3 V to 200 V range
• Offers lower thermal resistance compared to equivalent axial-leaded packages
• Compatible with standard surface-mount mounting processes

Single Zener Diodes Applications

• High-density circuit board mounting
• Low-profile electronic assembly
• Voltage regulation circuits requiring 3 W power handling

Single Zener Diodes Procurement Notes

Verify the specific suffix 'A' indicates the required 10% tolerance, as other suffixes exist for different accuracies. Confirm the 'TR13' designation matches the reel quantity requirements for automated assembly lines. Ensure the DO-214AC footprint aligns with the target PCB design specifications before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 120 V regulation point is needed with higher power handling than standard 1.5 W axial devices. The SMAJ package allows for reduced thermal resistance. Verify that the ±10% tolerance meets the circuit's precision requirements, as tighter tolerances are available via different part number suffixes.

Single Zener Diodes Part Context

This part belongs to the SMAJ5913 through SMAJ5956 series of surface mount Zener diodes. These devices serve as surface-mount equivalents to the JEDEC registered 1N5913B through 1N5956B series, offering identical electrical characteristics but with a 3.0 W rating instead of 1.5 W due to improved thermal performance.

Single Zener Diodes Replacement Considerations

The SMAJ5951AE3/TR13 is electrically equivalent to the 1N5951B series. Designers replacing axial components should account for the change from DO-41 to DO-214AC footprints while maintaining the 120 V and 3 W specifications.
