STPS20L25CG

Diode Arrays Overview

The STPS20L25CG is a dual common cathode Schottky rectifier manufactured by STMicroelectronics. It features a maximum average forward current of 10 A and a repetitive peak reverse voltage of 25 V. The device exhibits a low forward voltage drop of 560 mV at rated current, with a peak non-repetitive forward surge current capability of 220 A. Reverse leakage current is specified at 800 uA. It operates within a junction temperature range of -65 °C to +150 °C and is housed in a D2PAK-3 (TO-263-3) surface-mount package.

Diode Arrays Feature Summary

• Dual common cathode configuration for center-tap applications
• Low forward voltage drop for reduced power dissipation
• Specified avalanche capability for robust operation

Diode Arrays Applications

• Rectification at the secondary of 3.3 V SMPS units
• High frequency DC to DC converters
• Switched Mode Power Supplies

Diode Arrays Procurement Notes

Verify the specific suffix 'G' against official documentation to confirm compliance status or packaging variations. Ensure the D2PAK-3 footprint matches the target PCB design. Cross-reference the 10 A rating with system thermal requirements, as this differs from other variants in the series. Confirm RoHS compliance details directly from the manufacturer datasheet before finalizing procurement.

Diode Arrays Selection Notes

Select this component when a dual Schottky rectifier is required for low-voltage, high-efficiency power conversion. The 25 V rating suits 3.3 V output stages. The D2PAK-3 package offers a balance between thermal performance and surface-mount convenience. Compare the 10 A continuous current limit against load profiles to ensure adequate margin under peak conditions.

Diode Arrays Part Context

This part belongs to the STPS20L25C series of low-drop power Schottky rectifiers. While sharing similar electrical characteristics with through-hole variants like the STPS20L25CT, the CG suffix denotes the specific D2PAK-3 surface-mount package. This series is optimized for efficiency in switched-mode power supplies where low conduction losses are critical.

Diode Arrays Replacement Considerations

The STPS20L25CT serves as a pin-compatible through-hole alternative within the same series. Verify that the package type change does not impact thermal management strategies. Ensure the replacement maintains the dual common cathode configuration and identical voltage/current ratings.
