Diode Arrays Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm the device status as active through official STMicroelectronics channels before finalizing procurement plans. Ensure compatibility with D2PAK footprint requirements during PCB design validation.

Diode Arrays Selection Notes

Select this component for applications requiring low forward voltage drop at high currents. The dual center tap structure is ideal for synchronous rectification or standard free-wheeling topologies. Consider the thermal performance in the D2PAK package relative to the expected ambient temperature and heat sinking capabilities of the target system.

Diode Arrays Part Context

This part belongs to STMicroelectronics' Power Schottky Rectifier family, specifically the STPS series. These devices are engineered for efficiency in power conversion systems. The STPS2545CG-TR represents a higher current variant within the 45V rating class, complementing lower current models like the STPS1045 series.

Diode Arrays Replacement Considerations

Check for direct pin-compatible replacements within the same STPS 45V series, such as the STPS2545C. Verify that any substitute maintains the same D2PAK package and electrical ratings for current and voltage.
