• Free-wheeling diodes in low voltage high frequency inverters
• Polarity protection circuits

Diode Arrays Procurement Notes

Verify the specific suffix 'G-TR' against official ST documentation to confirm reel packaging and RoHS compliance status. Ensure the TO-263 footprint matches your PCB design constraints. Cross-reference the 30A/30V ratings with your thermal management requirements to prevent overheating during continuous operation.

Diode Arrays Selection Notes

Select this component when a dual Schottky rectifier is required for low-voltage, high-current applications. The TO-263 package offers superior thermal dissipation compared to smaller SMD packages. Consider the 30V rating margin relative to your input voltage peaks. Evaluate the 840mV forward voltage impact on overall power loss at your expected load currents.

Diode Arrays Part Context

This part belongs to the STPS30L30C series of dual Power Schottky Rectifiers designed for switch mode power supplies and high-frequency DC-DC converters. The series utilizes silicon technology and is available in multiple packages including TO-220AB, D2PAK, and I2PAK. The TO-263 variant provides a balance between current handling and surface-mount convenience.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include STPS30L30C (through-hole), STPS30L30CR (I2PAK), and STPS3030C (TO-220AB). Verify pinout compatibility and thermal resistance differences before substituting. Ensure any replacement maintains the 30V/30A rating and dual common cathode configuration.
