DSSK20-0045B

Diode Arrays Overview

The IXYS DSSK20-0045B is a silicon Schottky rectifier diode module designed for high-reliability power applications. It features a common cathode configuration with two elements housed in an isolated TO-220AB plastic package. The device supports a repetitive reverse voltage of 45V and provides a continuous forward current of 10A per element. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 140A, a typical forward voltage drop of 0.56V at rated current, and a maximum operating junction temperature of 175°C. The component is RoHS compliant and suitable for through-hole mounting.

Diode Arrays Feature Summary

• Utilizes Schottky barrier technology to achieve low forward voltage drop and minimal switching losses.
• Features an isolated case design compatible with standard heatsinking methods without additional insulators.
• Constructed with planar passivated chips for enhanced ruggedness and long-term reliability.

Diode Arrays Applications

• High-frequency DC-DC converters
• Free-wheeling diodes in motor drives
• Low-voltage high-current power supplies

Diode Arrays Procurement Notes

Verify the specific suffix against official Littelfuse or IXYS documentation to confirm exact binning or revision status. Ensure the procurement channel provides valid traceability records. Confirm that the TO-220AB package dimensions match the target PCB footprint requirements before finalizing orders.

Diode Arrays Selection Notes

Select this component when low forward voltage drop is critical for efficiency in low-voltage circuits. The 175°C junction temperature rating allows for operation in higher ambient environments compared to standard silicon rectifiers. Consider the thermal resistance of the isolated package when designing the heatsink interface.

Diode Arrays Part Context
