DSEI2X161-12P

Diode Arrays Overview

The DSEI2X161-12P is a dual independent fast recovery epitaxial diode (FRED) module manufactured by IXYS. It features a peak reverse repetitive voltage of 1200V and a maximum continuous forward current of 128A per leg, totaling 320A in the package configuration. The device exhibits a very short reverse recovery time and low forward voltage drop, optimized for high-efficiency power conversion. It utilizes planar glass passivated chips to ensure robust performance under thermal stress. The component is housed in an ECO-PAC2 chassis mount package with leads suitable for printed circuit board soldering, providing an isolation voltage of 3600V between terminals.

• Low forward voltage drop to minimize conduction losses

Diode Arrays Applications

• High-power DC-DC converters
• Induction heating systems
• Uninterruptible power supplies (UPS)

Diode Arrays Procurement Notes

Verify the specific suffix '12P' against official IXYS documentation to confirm pinout and mechanical dimensions match the ECO-PAC2 standard. Ensure that the sourcing channel provides original manufacturer packaging or verified authenticity certificates, as counterfeit power modules can exhibit significant deviations in thermal resistance and electrical characteristics compared to genuine components.

Diode Arrays Selection Notes

Select this component when designing circuits requiring high voltage blocking capability combined with high current handling in a compact form factor. The dual independent configuration allows for flexible bridge or half-bridge topologies. Consider the thermal management requirements associated with the chassis mount style and the specific switching frequency limitations imposed by the fast recovery characteristics to optimize system efficiency.

Diode Arrays Part Context

This part belongs to the DSEI series of fast recovery diodes from IXYS, designed for industrial and commercial power applications. The series emphasizes high reliability and efficiency through advanced epitaxial layer technology. The ECO-PAC2 packaging family offers standardized mounting solutions for various current ratings, facilitating easier integration into existing power electronics designs compared to discrete component assemblies.

Diode Arrays Replacement Considerations

Cross-reference with DSEI2X161-12A or similar variants in the DSEI2X161 series if pin compatibility differs. Verify electrical parameters such as Vrrm and If against the new candidate to ensure no derating is required in the existing thermal design.
