Overview
The 80CNQ045SMS2 is a Schottky diode array manufactured by SMC Diode Solutions, featuring a common cathode configuration with one pair of diodes. It is rated for a maximum DC reverse voltage (Vr) of 45 V and an average rectified current (Io) of 80 A per diode. The device utilizes the PRM2-SM surface-mount package. Key electrical characteristics include a forward voltage (Vf) of 740 mV at 80 A and a reverse leakage current of 5 mA at 45 V. The junction operating temperature range extends from -55°C to 175°C.
Feature Summary
- Schottky technology provides fast recovery speed characteristics suitable for high-frequency applications.
- Common cathode dual-diode configuration simplifies circuit design for bridge or synchronous rectification topologies.
- Surface-mount PRM2-SM package facilitates automated assembly and compact board layout.
Applications
- DC-DC converter output rectification
- Free-wheeling diodes in power supply circuits
- Solar panel bypass protection
Procurement Notes
Verify the specific suffix SMS2 against official datasheets to confirm the surface-mount variant and pinout compatibility. Ensure thermal management solutions align with the PRM2-SM package specifications for the intended operating environment. Cross-reference manufacturer part numbers to avoid confusion with chassis-mount equivalents.
Selection Notes
Select this component when a 45 V rating and 80 A current capacity are required in a surface-mount form factor. Compare forward voltage drop and thermal resistance against alternative packages like PRM2 if space constraints differ. Confirm that the 175°C junction temperature rating meets the system's thermal design requirements.
Part Context
This part belongs to the 80CNQ series of Schottky rectifiers from SMC Diode Solutions. The series offers various voltage ratings and current capacities in both chassis-mount and surface-mount configurations. The 80CNQ045SMS2 specifically addresses the need for high-current, low-voltage rectification in compact PCB designs.
Replacement Considerations
Direct substitutes may include other 80A 45V Schottky arrays in similar surface-mount packages. Verify pin compatibility and thermal performance before substitution. Check for obsolescence notices on the original part number.
