DSSK28-0045B

Diode Arrays Overview

The DSSK28-0045B 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 at a case temperature of 135°C. The device supports a non-repetitive peak surge current (IFSM) of 320 A and operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a typical forward voltage drop (VF) of 0.43 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

Diode Arrays Procurement Notes

Verify component authenticity through authorized IXYS distributors or Littelfuse channels. Confirm the specific package variant (TO-220AB or TO-263AB) matches the design requirements. Check for RoHS compliance status as indicated in official documentation. Ensure handling procedures account for the specified mounting torque if utilizing the B-type version.

Diode Arrays Selection Notes

Select this component for low-voltage, high-efficiency rectification tasks where minimal forward voltage drop is critical. Evaluate thermal management capabilities based on the RthJC value and expected ambient conditions. Consider the 45 V reverse voltage limit when designing circuits with potential voltage spikes. Verify compatibility with existing PCB footprints for the chosen package style.
