DSS2X101-015A

Diode Arrays Overview

The IXYS DSS2X101-015A is a high-power Schottky rectifier diode module featuring two independent diodes in one package. It utilizes the miniBLOC (SOT-227) chassis mount case for efficient thermal management. The device supports a maximum repetitive reverse voltage of 150V and a continuous load current of 100A per diode. Key electrical parameters include a maximum forward voltage of 0.99V and a peak forward impulse current rating of 1400A. The module provides an isolation voltage of 2500V and holds UL registration E72873.

Diode Arrays Feature Summary

• Dual independent Schottky diodes integrated into a single chassis-mount package
• High thermal efficiency via standard miniBLOC (SOT-227) mounting configuration
• Robust surge handling capability with high peak forward impulse current rating
• Electrical isolation between terminals and heatsink surface

Diode Arrays Applications

• High-current DC power supply rectification
• Industrial motor drive freewheeling circuits
• Battery charging systems requiring low forward voltage drop
• Welding equipment power stages

Diode Arrays Procurement Notes

Verify that the specific order matches the DSS2X101-015A designation, as the DSEI2X101-12A is a distinct switching diode variant within the same series family. Confirm the requirement for dual independent channels rather than a single bridge configuration. Ensure the application design accommodates the SOT-227 mechanical footprint and torque specifications for chassis mounting. Validate that the 150V reverse voltage rating aligns with the system's peak operating conditions.

Diode Arrays Selection Notes

Select this component when low forward voltage drop is critical for efficiency in high-current applications. The dual independent structure allows for flexible circuit topologies compared to standard bridge rectifiers. Consider the 150V voltage limit against potential transient spikes in the load. The miniBLOC package is suitable for direct heatsink attachment where high thermal conductivity is required. Evaluate the 100A continuous current rating against the RMS load requirements.

Diode Arrays Part Context

This part belongs to the DSS2X101 series of Schottky rectifier modules from IXYS. It shares the physical miniBLOC form factor with other high-power devices like the DSEI2X101 series but differs in technology, utilizing Schottky junctions instead of fast recovery pn-junctions. This distinction results in lower forward voltage but generally lower reverse voltage ratings compared to its switching diode counterparts.
