Diode Arrays Procurement Notes

Verify the complete part number including suffix B against official IXYS documentation to ensure correct pinout and thermal characteristics. Confirm that the TO-247AD package dimensions match your PCB footprint requirements. Check for any specific handling instructions regarding the epoxy material and thermal interface requirements for optimal heat dissipation performance.

Diode Arrays Selection Notes

Select this component when a dual Schottky configuration with common cathode topology is required. Ensure the system operating voltage remains below the 60 V reverse voltage limit. Consider the 20 A per diode current rating relative to thermal management capabilities. Verify that the low forward voltage characteristic aligns with efficiency targets for the specific power conversion application.

Diode Arrays Part Context

This device belongs to the DSSK series of dual Schottky diodes from IXYS. The series offers various voltage and current ratings packaged in standard international leads. The DSSK40-006B specifically addresses applications requiring moderate voltage blocking and high current capacity in a through-hole mounting format suitable for industrial power electronics.

Diode Arrays Replacement Considerations

Cross-reference with other dual Schottky diodes in the TO-247AD package. Verify electrical parameters such as VRRM, IFAV, and VF match or exceed original requirements. Ensure pin compatibility and thermal resistance specifications are comparable to maintain system performance and reliability.
