Single Zener Diodes Procurement Notes

Verify the specific suffix 'T3' indicates tape and reel packaging when ordering. Confirm that the part number corresponds to the 24V variant, as the series spans multiple voltages. Ensure compatibility with AEC-Q101 requirements if used in automotive contexts. Check for RoHS compliance status in the latest datasheet revision before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a 24V regulation point is required in a surface-mount design. The SMB package offers higher power handling than smaller SOD packages. Consider the ±5% tolerance for precision requirements. Verify thermal management needs given the 1W power rating and extended temperature range capabilities for harsh environments.

Single Zener Diodes Part Context

This part belongs to the 1SMB593x series of Zener diodes from onsemi. The series covers a wide voltage range from 3.3V to 200V. These devices are designed for general-purpose voltage regulation and protection. The SMB package provides a robust solution for applications requiring higher power dissipation compared to standard small-signal diodes.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 24V Zener voltage, 1W power rating, and SMB/DO-214AA package. Verify pinout compatibility and electrical characteristics such as impedance and leakage current. Automotive-grade equivalents should also hold AEC-Q101 qualification.
