DSA120C150QB

Diode Arrays Overview

The DSA120C150QB is a high-performance Schottky rectifier manufactured by Littelfuse (formerly IXYS). It features a common cathode configuration with two elements housed in a TO-3P package. The device supports a maximum repetitive reverse voltage of 150 V and an average forward current of 60 A per element. Key electrical characteristics include a low typical forward voltage of 0.8 V and a maximum non-repetitive peak forward surge current of 600 A. It operates within a temperature range of -55 °C to +175 °C.

Diode Arrays Feature Summary

• Extremely low forward voltage drop for reduced conduction losses
• Soft recovery characteristic minimizing switching noise and voltage peaks
• High reliability circuit operation with low reverse leakage current

Diode Arrays Applications

• Free wheeling diode applications in power converters
• High frequency DC-DC conversion circuits
• Uninterruptible Power Supply (UPS) systems

Diode Arrays Procurement Notes

Verify the manufacturer designation, as the component is produced by Littelfuse following the acquisition of IXYS. Confirm the specific suffix and package variant matches the required TO-3P form factor. Ensure the ordering quantity aligns with tube packaging standards. Validate RoHS compliance status against current regulatory requirements before finalizing procurement.

Diode Arrays Selection Notes

Select this component for designs requiring low conduction loss and fast switching speeds at 150 V ratings. The common cathode arrangement simplifies circuit topology for half-bridge or full-bridge configurations. Consider the thermal management capabilities of the TO-3P package for high-current continuous operation scenarios.

Diode Arrays Part Context

This device belongs to the Gen² Schottky Diode series, characterized by advanced silicon technology for superior efficiency. It serves as a replacement for legacy IXYS high-power rectifiers in industrial and automotive power electronics. The part integrates robust construction suitable for demanding environmental conditions.

Diode Arrays Replacement Considerations

Direct substitutes must match the 150 V rating, 60 A current capacity, and TO-3P dual common cathode configuration. Verify that alternative components exhibit comparable soft recovery behavior and forward voltage specifications to maintain system performance.
