CD611616B

Diode Arrays Overview

The Powerex CD611616B is a dual diode isolated POW-R-BLOK module rated for 160 Amperes and up to 2200 Volts. It features an electrically isolated heatsink design with a DBC alumina insulator and metal baseplate. The device supports repetitive peak reverse blocking voltages up to 2200 V, RMS forward currents of 250 A at 180° conduction, and average forward currents of 160 A. Operating temperatures range from -40°C to +150°C.

Diode Arrays Feature Summary

• Electrically isolated heatsinking eliminates the need for additional insulation components
• DBC alumina insulator provides low thermal impedance for improved current capability
• Glass passivated chips ensure robust performance within the isolated packaging

Diode Arrays Procurement Notes

Verify the specific voltage rating suffix (e.g., '16' for 1600V) against the datasheet table to confirm the exact part number configuration. Ensure mounting torque specifications are strictly followed during installation to maintain electrical isolation integrity and prevent mechanical failure. Confirm UL recognition status requirements for your specific application safety standards.

Diode Arrays Selection Notes

Select this module when high current rectification requires electrical isolation between the circuit and the common heatsink. The dual diode configuration is suitable for bridge circuits or half-bridge topologies. Verify that the required repetitive peak reverse voltage does not exceed 2200 V and that the thermal management system can handle the specified junction-to-case thermal resistance values.

Diode Arrays Part Context

This component belongs to the POW-R-BLOK Dual & Single Diode Isolated Module family manufactured by Powerex. The series offers various voltage ratings up to 2200 Volts and current ratings up to 160 Amperes. Other variants in the lineup include CS61, CN61, and CC61 series modules, sharing similar physical dimensions and isolation technologies.

Diode Arrays Replacement Considerations

Direct replacements must match the 160A current rating, 2200V voltage rating, and isolated package footprint. Cross-reference with other Powerex models like CC611616B for single diode configurations if topology changes are acceptable.
