SMBJ5934CE3/TR13

Single Zener Diodes Overview

The SMBJ5934CE3/TR13 is a surface mount 2.0 W Zener diode from the SMBJ59 family, equivalent to JEDEC registered 1N5918–1N5924 series but with a higher power rating due to lower thermal resistance. It features a DO-214AA (SMB) J-bend package for high-density mounting and offers a nominal Zener voltage of 24 V with a ±2% tolerance. The device operates within a junction temperature range of –65 °C to +150 °C and has a maximum dynamic impedance of 19 Ω at the test current of 26.3 mA.

Single Zener Diodes Feature Summary

• Surface mount design in DO-214AA package allows for greater PC board mounting density compared to axial equivalents.
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020F, requiring no dry pack storage.
• RoHS compliant devices feature e3 suffix indicating matte-tin plating.
• Provides identical electrical characteristics to prior axial-lead JEDEC registered series.

Single Zener Diodes Applications

• Voltage regulation over a broad operating current and temperature range
• High surge stress withstand applications
• Low-profile mounting in high-density PCB designs

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required voltage tolerance and power rating specifications. Confirm RoHS compliance status if leaded alternatives are not acceptable. Ensure ordering quantities align with standard tape and reel packaging requirements. Check for any recent product change notices or obsolescence announcements from the manufacturer before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a 2.0 W power rating is required in a compact surface mount footprint. The DO-214AA package is suitable for applications needing higher mounting density than axial leads allow. Consider the ±2% voltage tolerance for precision regulation needs. Verify thermal management capabilities as the maximum DC current depends on adequate heat sinking during operation.

Single Zener Diodes Part Context

This component belongs to the SMBJ59 family of silicon 2.0 Watt Zener diodes manufactured by Microchip Technology. The family covers Zener voltages from 5.1V to 9.1V for some variants, while others like this one cover higher voltages up to 200V. These diodes serve as surface mount equivalents to the traditional 1N59xx series, offering improved power handling due to lower thermal resistance in the plastic encapsulated package.

Single Zener Diodes Replacement Considerations

The SMBJ5934CE3/TR13 is electrically equivalent to the axial-lead 1N5934B series. For direct replacement, ensure the substitute component supports the same 2.0 W power rating and fits the DO-214AA footprint. Verify that any alternative maintains the required ±2% voltage tolerance and operates within the specified temperature range.
