DSS2X121-0045B

Diode Arrays Overview

The DSS2X121-0045B is a dual isolated Schottky rectifier manufactured by IXYS, now part of Littelfuse. It features two independent diodes in a single package with an isolation voltage of 2500 Vrms. The device supports a maximum repetitive reverse voltage of 45 V and an average forward current of 120 A per diode (240 A total). It utilizes the miniBLOC screw-mount package for efficient thermal management.

Diode Arrays Feature Summary

• Dual isolated configuration providing electrical separation between two independent Schottky diodes within a single unit
• High isolation voltage capability of 2500 Vrms ensuring safety and reliability in high-voltage applications
• UL registered component (E72873) meeting international safety standards for industrial power systems

Diode Arrays Applications

• High-frequency DC-DC converters requiring galvanic isolation
• Uninterruptible Power Supply (UPS) output rectification stages
• Industrial motor drive freewheeling circuits
• Solar inverter bridge configurations

Diode Arrays Procurement Notes

Verify manufacturer attribution carefully as IXYS was acquired by Littelfuse; datasheets may bear either brand. Confirm package integrity and pin alignment against the miniBLOC specification before integration. Check for recent Product Change Notices regarding manufacturing site transitions or material updates to ensure compliance with current supply chain requirements.

Diode Arrays Selection Notes

Select this component when high current density and electrical isolation are required in a compact form factor. The 45 V rating suits low-voltage, high-amperage applications. Ensure adequate heatsinking due to the 310 W power dissipation capability. Verify that the screw-mount mechanical interface matches the system's thermal design constraints.

Diode Arrays Part Context

This device belongs to the DSS2X series of high-power Schottky rectifiers designed for robust industrial environments. It represents a transition point where IXYS technology is integrated into Littelfuse’s broader power semiconductor portfolio, maintaining performance specifications while updating documentation and support structures.
