Overview
The 80CNQ040SM is a Schottky diode array manufactured by SMC Diode Solutions, featuring one pair of common cathodes. It supports an average rectified current of 40A per diode and withstands a maximum DC reverse voltage of 40V. The component utilizes the PRM2-SM through-hole package for base mounting. Key electrical specifications include a forward voltage of 740 mV at 80 A and a reverse leakage current of 5 mA at 40 V. It operates within a junction temperature range of -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-diode applications.
- Robust epoxy encapsulation provides enhanced mechanical strength and moisture resistance.
- Through-hole PRM2-SM package facilitates secure base mounting in power modules.
Applications
- DC-DC converter circuits
- Free-wheeling rectification in motor drives
- Power supply output rectification
Procurement Notes
Verify the specific suffix SM against the official datasheet to confirm the PRM2-SM package variant and pinout compatibility. Ensure the selected component meets the required thermal management standards for the intended operating environment. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability before finalizing procurement orders.
Selection Notes
Select this component when a 40V reverse voltage rating and 40A continuous current capacity are required in a common cathode arrangement. The PRM2-SM through-hole package is suitable for applications requiring robust mechanical mounting on heat sinks or chassis. Consider the 175°C junction temperature rating for high-temperature operational environments compared to standard 150°C alternatives.
Part Context
This device belongs to the 80CNQ series of Schottky diode arrays from SMC Diode Solutions. The series is designed for high-efficiency power conversion applications. The 80CNQ040SM specifically denotes the 40V voltage rating variant within this family, sharing similar structural characteristics with other models like the 80CNQ030SM but differing in breakdown voltage specifications.
Replacement Considerations
Compatible substitutes include the 80CNQ030SM for lower voltage requirements or the 80CNQ040SL if the SL package variant is acceptable. Verify that any replacement maintains the same current rating, package dimensions, and thermal performance characteristics to ensure circuit integrity.
