DSSK30-0045B

Diode Arrays Overview

The DSSK30-0045B is a power Schottky rectifier with a common cathode configuration, manufactured by IXYS. It features a maximum repetitive reverse voltage (VRRM) of 45 V and an average forward current (IFAV) rating of 15 A per device at a case temperature of 135°C, totaling 30 A for the dual element structure. The component utilizes an international standard TO-247 AD package. Key electrical characteristics include a typical forward voltage drop (VF) of 0.42 V at 15 A and 125°C, and a thermal resistance from junction to case (RthJC) of 1.4 K/W.

Diode Arrays Feature Summary

• Very low forward voltage drop (VF) for reduced conduction losses
• Extremely low switching losses due to Schottky technology
• Low reverse leakage current (IR) values
• Epoxy material meets UL 94V-0 flammability rating

Diode Arrays Applications

• Rectifiers in switch mode power supplies (SMPS)
• Free wheeling diodes in low voltage converters

Diode Arrays Procurement Notes

Verify the specific manufacturer source, as IXYS has undergone corporate acquisitions. Confirm the component status, as documentation indicates it may be designated 'Not for new design'. Ensure the TO-247 AD package dimensions match the target PCB layout requirements before finalizing procurement decisions.

Diode Arrays Selection Notes

Select this component for applications requiring low voltage rectification with high efficiency. The common cathode arrangement simplifies circuit topology for dual-rail or bridge configurations. Evaluate the thermal management strategy based on the RthJC value to ensure the junction temperature remains within the specified -55°C to +150°C operating range under expected load conditions.

Diode Arrays Part Context

This component belongs to the DSSK series of power Schottky rectifiers from IXYS. These devices are designed for high-reliability circuit operation, offering low noise switching and reduced voltage peaks. The series is characterized by its ability to minimize protection circuit complexity while maintaining low overall system losses in power conversion environments.

Diode Arrays Replacement Considerations

Officially recommended replacements include the DSB30C45HB and DSB60C45HB. Verify pinout compatibility and thermal performance specifications when substituting these parts.
