DGSK40-018A

Diode Arrays Overview

The DGSK40-018A is a Gallium Arsenide Schottky rectifier diode manufactured by IXYS. It features a maximum repetitive reverse voltage (VRRM) of 180 V and a forward average current (IFAV) rating of 23 A at a case temperature of 25°C, decreasing to 17 A at 90°C. The device utilizes a TO-220AB package with a single common cathode configuration. Key electrical characteristics include a typical junction capacitance of 33 pF and a maximum non-repetitive peak surge current of 30 A. The component supports a wide operating junction temperature range from -55°C to +175°C.

Diode Arrays Procurement Notes

Verify the specific suffix designation against official documentation to confirm the exact package variant, as the datasheet distinguishes between standard and surface-mount versions. Confirm that the procurement channel provides original manufacturer components to ensure reliability in high-frequency applications. Check for updated revision notices regarding thermal resistance values or mounting torque specifications before finalizing orders.

Diode Arrays Selection Notes

Select this component for designs requiring fast recovery and minimal reverse recovery charge. Ensure the thermal management system can maintain the case temperature within limits to sustain the rated 23 A current. Consider the 180 V blocking capability when designing circuits with potential voltage spikes. Verify that the TO-220AB footprint matches the PCB layout requirements for the specific package version ordered.

Diode Arrays Part Context

This part belongs to the DGS/DGSK series of Gallium Arsenide Schottky rectifiers from IXYS. The series is designed to replace traditional silicon rectifiers in high-frequency applications where efficiency and switching speed are critical. The GaAs technology provides superior performance compared to standard silicon diodes, particularly in reducing switching losses.
