DSIK45-16AR

Diode Arrays Overview

The DSIK45-16AR is a standard recovery rectifier diode array manufactured by IXYS. It features a common cathode configuration with two individual diodes housed in an ISOPLUS247 (TO-247-3) through-hole package. The device supports a maximum repetitive peak reverse voltage of 1600 V and an average forward current of 45 A per diode. Key electrical characteristics include a maximum non-repetitive surge current of 800 A, a typical forward voltage drop of 1.55 V at rated current, and a maximum reverse leakage current of 10 µA. The component operates within a junction temperature range of -55°C to +175°C.

Diode Arrays Feature Summary

• Dual diode common cathode configuration for efficient bridge or push-pull circuit implementation
• Planar glass-passivated chips ensuring stable operation and high reliability under thermal stress
• ISOPLUS247 package design providing robust mechanical mounting and effective heat dissipation capabilities

Diode Arrays Applications

• Industrial motor drive systems requiring high-voltage rectification
• Uninterruptible power supply (UPS) input stages
• High-power DC-DC converter topologies

Diode Arrays Procurement Notes

Verify the specific suffix 'AR' indicates the isolated version with UL registration E153432 when sourcing replacements. Confirm that the TO-247-3 pinout matches the target PCB footprint, as lead configurations can vary between manufacturers. Ensure the procurement channel provides original manufacturer documentation to validate the planar glass-passivation process and absolute maximum ratings against counterfeit risks.

Diode Arrays Selection Notes

Select this component for applications demanding high voltage blocking capability combined with moderate current handling in a single package. The common cathode arrangement simplifies layout compared to discrete diodes. Consider the thermal resistance of the ISOPLUS247 package when designing heatsinking solutions. Evaluate the reverse recovery characteristics if the application involves high-frequency switching, as this is a standard recovery device rather than a fast or ultra-fast variant.

Diode Arrays Part Context

This part belongs to IXYS's DSIK series of high-power rectifier arrays designed for industrial and automotive-grade environments. The series utilizes planar chip technology to minimize leakage currents and improve ruggedness. The DSIK45-16AR specifically targets the 1600V segment, offering a balance between voltage rating and current capacity suitable for medium-to-high power conversion systems where space efficiency and thermal performance are critical design constraints.

Diode Arrays Replacement Considerations

Direct substitutes must match the 1600V/45A rating, common cathode configuration, and TO-247-3 package. Verify equivalent thermal resistance and forward voltage characteristics to ensure system compatibility.
