160CMQ035

Overview

The SMC Diode Solutions 160CMQ035 is a high-power Schottky diode array configured as one pair of common cathodes. It features a maximum DC reverse voltage (Vr) of 35 V and an average rectified forward current (Io) of 160 A per diode. The device utilizes PRM4 chassis mount packaging for robust thermal management. Key electrical specifications include a maximum forward voltage (Vf) of 990 mV at 200 A and a reverse leakage current of 20 mA at 35 V. The junction temperature range spans from -55°C to 150°C, ensuring reliable operation in demanding power conversion environments.

Feature Summary

• Schottky barrier technology enables fast switching characteristics with minimal reverse recovery charge.
• Common cathode dual configuration simplifies circuit design for full-wave or bridge rectification applications.
• PRM4 chassis mount package provides low thermal resistance for efficient heat dissipation in high-current scenarios.

Applications

• High-current DC power supply rectification
• Free-wheeling diodes in motor drive circuits
• DC-DC converter output rectification

Procurement Notes

Verify the specific suffix and marking code on the physical component against the official SMC Diode Solutions datasheet to confirm the 160A rating and 35V voltage class. Ensure that the procurement source provides valid RoHS compliance documentation and original manufacturer traceability records. Confirm that the PRM4 mounting interface matches your thermal management system requirements before finalizing orders.

Selection Notes

Select this component when designing systems requiring high average current handling with low forward voltage drop at 35V reverse bias. Compare thermal resistance values against your heatsink capabilities to ensure junction temperatures remain within the 150°C limit under peak load conditions. Consider the common cathode topology for simplified layout compared to discrete single-diode solutions in high-power density designs.

Part Context

This part belongs to the CMQ series of high-current Schottky diode arrays from SMC Diode Solutions. The series is engineered for industrial and automotive power electronics where reliability under high thermal stress is critical. The 160CMQ035 variant specifically addresses applications needing substantial current capacity at lower voltage levels, distinguishing it from higher-voltage counterparts in the same product family.

Replacement Considerations

Direct substitutes must match the 160A current rating, 35V reverse voltage, and PRM4 chassis mount form factor. Verify pinout compatibility and thermal interface dimensions to ensure mechanical fit without redesigning the PCB or heatsink assembly.
