84CNQ035S2

Overview

The 84CNQ035S2 is a Schottky diode array manufactured by SMC Diode Solutions, featuring a one-pair common cathode configuration. It is designed for chassis mounting in the PRM2 package. The device supports a maximum DC reverse voltage of 35 V and an average rectified current of 80 A per diode. Key electrical parameters include a forward voltage of 600 mV at 80 A and a reverse leakage current of 20 mA at 35 V. The junction operating temperature range extends from -55°C to 150°C.

Feature Summary

• Utilizes Schottky technology for fast recovery characteristics with minimal switching losses.
• Features a robust chassis mount design suitable for high-power thermal management.
• Provides a common cathode configuration for efficient bridge or full-wave rectification circuits.

Applications

• High-current DC power supply rectification
• Industrial motor drive freewheeling applications
• Battery charging systems requiring low forward voltage drop

Procurement Notes

Verify the specific suffix 'S2' against the manufacturer datasheet to confirm exact thermal and mechanical specifications, as suffixes often denote variations in lead plating or packaging standards. Ensure compatibility with chassis mounting hardware specified in the PRM2 package dimensions. Cross-reference the RoHS3 compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a high-current 80 A rating and low 35 V blocking voltage are required in a single dual-diode module. The PRM2 chassis mount form factor is ideal for applications where direct heat sinking to a cold plate or heatsink is necessary. Consider the 600 mV forward voltage drop for efficiency calculations in low-voltage, high-amperage output stages.

Part Context

This part belongs to the CNQ series of high-power Schottky rectifiers from SMC Diode Solutions. The series is engineered for demanding industrial and automotive environments, offering superior performance over standard PN junction diodes due to lower forward voltage and faster switching speeds. The PRM2 package provides a standardized footprint for easy integration into existing power modules.

Replacement Considerations

Direct substitutes within the same family include the 81CNQ035SMS2 and 82CNQ030S2, though these differ in current ratings or voltage specifications. Verify that any replacement maintains the PRM2 chassis mount interface and matches the 35 V reverse voltage requirement to ensure circuit integrity.
