SMAJ4466CE3/TR13

Single Zener Diodes Overview

The SMAJ4466CE3/TR13 is a 1.5-watt Zener diode manufactured by Microsemi Corporation in the DO-214AC (SMAJ) surface-mount package. It features a nominal Zener voltage of 11 volts with a ±2% tolerance, indicated by the 'C' suffix. The device operates within a temperature range of -55°C to +150°C and includes stress-relief J-bend contacts for improved thermal efficiency and placement reliability.

Single Zener Diodes Feature Summary

• Provides superior surge protection against ESD and electrical fast transients per IEC standards
• Features thermally efficient design with lower junction temperatures
• Includes stress-relief J-bend contacts for easier automatic handling

Single Zener Diodes Applications

• High reliability voltage regulation in low profile surface mount locations
• Airborne or satellite applications requiring lightweight components
• Protection from ESD and EFT transients in electronic circuits

Single Zener Diodes Procurement Notes

Verify the specific ordering suffixes to confirm compliance requirements. The 'e3' suffix indicates RoHS compliance. Confirm that the component matches the required ±2% tolerance designation. Ensure the package type aligns with the intended PCB layout specifications before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 11-volt reference is required in a compact surface-mount form factor. The device offers enhanced mechanical stability through its J-bend contact design. Consider the thermal derating characteristics for high-temperature environments where power dissipation limits must be strictly observed.

Single Zener Diodes Part Context

This part belongs to the SMAJ4460 thru SMAJ4496 series of 1.5-watt Zener diodes. The series meets or exceeds the performance of traditional axial equivalents like the 1N4466. It utilizes a larger active die element to provide double the overall surge performance compared to standard MELF style packages.

Single Zener Diodes Replacement Considerations

The SMAJ4466CE3/TR13 serves as a direct surface-mount replacement for the 1N4466 axial Zener diode. Verify that the receiving circuit can accommodate the DO-214AC footprint dimensions and polarity markings.
