Overview
The SMC Diode Solutions 80CNQ040SMS2 is a Schottky rectifier module in the PRM2-SM package. It features a 40 V DC blocking voltage and an average rectified forward current of 40 A per leg (80 A total). The device operates with a junction temperature range of -55°C to +150°C. Electrical characteristics include a typical forward voltage drop of 0.64 V at 80 A and a maximum reverse leakage current of 5 mA at 25°C. The module utilizes pure tin-dipped terminals for mounting.
Feature Summary
- Center tap configuration designed for high frequency operation
- Guard ring structure provides enhanced ruggedness and long term reliability
- High purity, high temperature epoxy encapsulation ensures mechanical strength and moisture resistance
Applications
- Switching power supplies
- Converters
- Free-wheeling diodes
- Reverse battery protection
Procurement Notes
Verify the specific ordering suffix SMS2 to confirm the terminal finish is pure tin dipped rather than nickel plated. Confirm the package style matches the PRM2-SM dimensions required for your thermal management design. Ensure the requested quantity aligns with standard shipping configurations provided by the manufacturer.
Selection Notes
Select this component when a center tap topology is required for low forward voltage drop applications. The PRM2-SM package offers a low profile suitable for high current density designs. Verify that the 40 A per leg rating meets the continuous load requirements of the target circuit under specified thermal conditions.
Part Context
This part belongs to the 80CNQ series of Schottky rectifiers manufactured by SMC Diode Solutions. The series includes variants with different voltage ratings such as 35 V and 45 V. The 80CNQ040SMS2 specifically denotes the 40 V rating and the SM package variant with specific terminal finishing.
Replacement Considerations
Compatible substitutes within the same series include the 80CNQ040SM and 80CNQ040S2. These alternatives share identical electrical specifications but differ in terminal finish and packaging details. Verify mechanical compatibility before substitution.
