Overview
The 80CNQ045S2 is a Schottky rectifier diode module manufactured by SMC Diode Solutions. It features a common cathode configuration with two elements, rated for a maximum repetitive reverse voltage of 45 V and an average forward current of 80 A per diode. The device utilizes the PRM2 package for chassis mounting. Key electrical characteristics include a maximum forward voltage of 740 mV at 80 A and a maximum reverse leakage current of 5 mA at 45 V. The junction temperature range spans from -55°C to 175°C.
Feature Summary
- Schottky technology provides low forward voltage drop and high-frequency operation capabilities.
- Common cathode dual-element design simplifies circuit layout for bridge or center-tap applications.
- High purity epoxy encapsulation enhances mechanical strength and moisture resistance.
Applications
- Switching power supplies
- DC-DC converters
- Free-wheeling diodes in inductive load circuits
Procurement Notes
Verify the specific suffix 'S2' against official SMC Diode Solutions documentation to confirm exact pinout and thermal interface specifications. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity. Confirm RoHS3 compliance status and REACH registration details prior to finalizing orders for regulatory adherence.
Selection Notes
Select this component when a robust, high-current Schottky solution is required for chassis-mounted applications. The PRM2 package offers a compact footprint suitable for space-constrained designs. Evaluate thermal management requirements based on the 175°C junction temperature rating and ensure adequate heatsinking for sustained 80 A operation.
Part Context
This part belongs to the 80CNQ series of Schottky rectifier modules from SMC Diode Solutions. The series is designed for general-purpose rectification and free-wheeling applications requiring high reliability. The PRM2 package is a standard form factor for medium-to-high current chassis-mount diodes within the manufacturer's portfolio.
Replacement Considerations
Cross-reference with other 80A 45V Schottky modules in the PRM2 package. Verify that alternative parts match the common cathode configuration and thermal resistance characteristics. Check for equivalent forward voltage and reverse leakage specifications to ensure circuit compatibility.
