Diode Arrays Procurement Notes

Verify the specific suffix 'CT' against the manufacturer datasheet to confirm packaging details, as standard variants may differ. Confirm RoHS compliance status and check for end-of-life notifications or active production status before finalizing procurement plans. Ensure the TO-220-3 lead form matches the target PCB footprint requirements.

Diode Arrays Selection Notes

Select this component for low-voltage, medium-current applications requiring high efficiency. The 40 V rating limits suitability for higher voltage systems. Consider the 3 A current limit per diode when designing for continuous load conditions. The TO-220-3 package requires adequate heatsinking if operating near maximum thermal limits.

Diode Arrays Part Context

This part belongs to the STPS64 series of power Schottky rectifiers from STMicroelectronics. The series includes various voltage and current ratings packaged in options like DPAK, I²PAK, and TO-220. These devices are engineered for general-purpose rectification in power electronics where speed and efficiency are critical.

Diode Arrays Replacement Considerations

Consult official substitution guides for equivalent parts within the same voltage and current class. Verify pinout compatibility and thermal performance metrics before replacing. Generic equivalents may not match the specific switching characteristics or avalanche rating of the original component.
