SMBJ5943CE3/TR13

Single Zener Diodes Overview

The SMBJ5943CE3/TR13 is a surface mount 2.0 W Zener diode from Microchip Technology, housed in the DO-214AA (SMB) package. It serves as an equivalent to the JEDEC registered 1N5924 series with identical electrical characteristics but offers a higher power rating due to lower thermal resistance. The device features a nominal Zener voltage of 56 V with a tolerance of +/- 10%. It operates within a junction temperature range of -65 °C to +150 °C and includes RoHS compliant matte-tin plating.

Single Zener Diodes Feature Summary

• Surface mount design in DO-214AA package for high-density mounting
• Equivalent to axial-lead 1N5924 series with 2.0 W power rating
• Moisture classification Level 1 requiring no dry pack
• RoHS compliant matte-tin plating

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• Protection against high surge stresses
• Applications requiring minimal voltage change versus current variations

Single Zener Diodes Procurement Notes

Verify the specific part number suffix against official Microchip documentation to confirm plating type and packaging configuration. Ensure compatibility with the required Zener voltage and tolerance specifications for the target circuit design. Confirm availability status directly with authorized distributors or the manufacturer, as production statuses may change.

Single Zener Diodes Selection Notes

Select this component when a 2.0 W surface mount Zener diode is required as a direct replacement for the 1N5924 series. Consider the DO-214AA package dimensions for PCB layout constraints. Verify that the 56 V nominal voltage and 10% tolerance align with the circuit's regulation requirements and thermal management capabilities.
