Overview
The 84CNQ040SMS2 is a Schottky rectifier diode array manufactured by SMC Diode Solutions. It features a single pair of common cathodes with a maximum DC reverse voltage of 40 V and an average forward current of 80 A per diode. The device utilizes the PRM2-SM through-hole package. Key electrical parameters include a forward voltage of 740 mV at 80 A, a reverse leakage current of 5 mA at 35 V, and a fast recovery time of less than or equal to 500 ns for currents greater than 200 mA. The junction temperature range operates from -55°C to 175°C.
Feature Summary
- Schottky barrier technology ensures low forward voltage drop and high switching efficiency.
- Common cathode configuration simplifies circuit design for dual-channel applications.
- PRM2-SM through-hole package provides robust mechanical mounting for power electronics.
Applications
- High-frequency DC-DC converters
- Free-wheeling rectification in power supplies
- Polarity protection circuits
Procurement Notes
Verify the specific suffix SMS2 against the manufacturer's official datasheet to confirm RoHS compliance and lead-free status. Ensure the PRM2-SM package dimensions match the target PCB footprint. Confirm that the 80A current rating aligns with thermal management requirements in the final assembly.
Selection Notes
Select this component for applications requiring low forward voltage and fast recovery characteristics. The 40V rating suits low-voltage power systems. Compare thermal resistance and package compatibility against alternatives like the 81CNQ035SMS2 if voltage margins differ. Validate junction temperature limits under peak load conditions.
Part Context
This part belongs to the 84CNQ series of Schottky diode arrays from SMC Diode Solutions. The series focuses on high-current, low-voltage rectification using silicon carbide or advanced silicon technologies within the PRM2 family of packages designed for board-level integration.
Replacement Considerations
The 81CNQ035SMS2 serves as a potential substitute with similar current ratings but a lower 35V reverse voltage. Verify voltage headroom before substitution. Cross-reference pinouts and thermal characteristics to ensure functional equivalence in the existing circuit layout.
