Diode Arrays Procurement Notes

Verify the specific voltage rating suffix (e.g., 20 for 2000V) matches the application requirements before ordering. Confirm that the mounting torque specifications are strictly adhered to during assembly to prevent mechanical failure. Ensure the selected heatsink interface is compatible with the module's isolation requirements. Check for UL recognition status if required by end-use equipment regulations.

Diode Arrays Selection Notes

Select this module when high voltage isolation and robust thermal performance are critical. The dual diode configuration suits bridge rectifier applications requiring compact packaging. Evaluate the thermal resistance values against the expected ambient temperatures and heat dissipation capabilities of the chosen heatsink system. Consider the physical dimensions and mounting hole patterns for integration into existing chassis designs.

Diode Arrays Part Context

This component belongs to the POW-R-BLOK family of single and dual diode isolated modules manufactured by Powerex. The series offers various voltage ratings from 2000V to 2500V while maintaining a consistent 100A current rating. These modules are engineered for industrial power conversion systems where reliable rectification and electrical isolation are paramount.

Diode Arrays Replacement Considerations

Direct substitutes within the same POW-R-BLOK series include CS412099C, CC412099C, and CN412099C, which share identical electrical ratings but may differ in pinout or terminal configurations. Verify mechanical compatibility and thermal interface requirements when considering alternative part numbers from other manufacturers.
