DSSK28-0045BS-TRL

Diode Arrays Overview

The DSSK28-0045BS-TRL is a Schottky diode array manufactured by IXYS, designed for surface-mount applications. It features a common cathode configuration with two individual diodes housed in a TO-263-3 (D2PAK) package. The device supports a maximum repetitive peak reverse voltage of 45 V and an average forward current of 15 A per diode. Key electrical characteristics include a typical forward voltage of 570 mV at 10 A and a maximum reverse leakage current of 100 µA at 45 V. It operates within a junction temperature range of -55°C to 150°C.

Diode Arrays Feature Summary

• Schottky barrier technology enables high switching efficiency and low forward voltage drop.
• Common cathode dual-diode configuration simplifies circuit design for synchronous rectification.
• Robust TO-263-3 surface-mount package provides efficient thermal dissipation.

Diode Arrays Applications

• DC-DC converter output rectification
• Synchronous rectifier circuits
• Free-wheeling diodes in power supplies

Diode Arrays Procurement Notes

Verify the specific suffix 'TRL' indicates tape-and-reel packaging when sourcing components. Confirm that the manufacturer designation remains IXYS or Littelfuse depending on the supply chain timeline. Ensure compatibility with standard reflow soldering profiles for the TO-263-3 package during assembly planning.

Diode Arrays Selection Notes

Select this component for applications requiring low forward voltage and fast recovery times at moderate currents. The 45 V rating suits low-voltage DC systems. Compare thermal resistance requirements against system constraints to ensure adequate heat sinking or PCB copper area utilization for reliable operation under load.

Diode Arrays Part Context

This part belongs to the IXYS diode array family, specifically utilizing Schottky technology for improved performance over standard PN junctions. The DSSK series is engineered for industrial and consumer power management solutions where size and efficiency are critical. It complements other IXYS discrete semiconductor products for complete power stage designs.

Diode Arrays Replacement Considerations

The MBRB2045CT-TP from Micro Commercial Components is a documented alternative with identical 45 V, 20 A specifications and TO-263AB packaging. Verify pinout compatibility and thermal characteristics before substitution.
