STPS40SM120CT

Diode Arrays Overview

The STPS40SM120CT is a dual common cathode Schottky rectifier manufactured by STMicroelectronics. It features two silicon elements in an I2PAK-3 package with the case connected to the cathode. Key electrical parameters include a maximum forward voltage of 0.79 V and a non-repetitive peak forward current of 220 A. The device operates at a maximum junction temperature of 150 °C.

Diode Arrays Feature Summary

• Dual common cathode configuration for bridge or full-wave applications
• Low forward voltage drop for improved efficiency
• High frequency operation capability

Diode Arrays Applications

• High frequency switch mode power supplies
• Notebook adapters
• Game station power units
• Desktop adapters

Diode Arrays Procurement Notes

Verify the specific suffix 'CT' against official STMicroelectronics documentation, as standard listings often reference 'ST'. Confirm the package type matches the required I2PAK-3 footprint. Ensure the component meets ECOPACK 2 compliance standards if environmental regulations apply to the design.

Diode Arrays Selection Notes

Select this component for medium power high-density adapter designs requiring low leakage current. The trade-off between voltage drop and leakage is optimized for notebook and desktop adaptors. Consider the 150 °C operating limit for thermal management in enclosed spaces.

Diode Arrays Part Context

This part belongs to the STPS series of low leakage power Schottky rectifiers. It is designed to provide good efficiency at both low and high load conditions. The series is commonly used in consumer electronics power supplies where space and thermal performance are critical constraints.

Diode Arrays Replacement Considerations

The STPS40SM120C is a related variant within the same product family. Verify pinout compatibility and package dimensions before substitution. Check if the specific 'CT' suffix denotes a distinct tape-and-reel specification compared to other suffixes.
