Overview
The PMEG4010CPAS-QX is a dual Schottky barrier rectifier in common cathode configuration, housed in an ultra-thin DFN2020D-3 (SOT1061D) leadless SMD package. It supports an average forward current of 1 A and a reverse voltage of 40 V. The device features a low forward voltage of up to 500 mV at 1 A and a maximum reverse current of 55 µA at 40 V. Thermal resistance from junction to ambient is 70 K/W on FR4 PCBs. The component includes an integrated guard ring for stress protection and visible solderable side pads.
Feature Summary
- Dual Schottky barrier rectifier with common cathode configuration
- Ultra-thin leadless DFN2020D-3 package with visible solderable side pads
- Integrated guard ring for enhanced stress protection
- Exposed heat sink cathode pad for improved thermal conductivity
Applications
- Low voltage rectification
- High efficiency DC-to-DC conversion
- Switch Mode Power Supply (SMPS)
- Free-wheeling application
- Reverse polarity protection
Procurement Notes
Verify the specific suffix '-QX' against official Nexperia documentation to confirm packaging details and any automotive qualification status, as standard PMEG4010CPAS variants are explicitly noted as non-automotive qualified. Ensure design-in compatibility with the DFN2020D-3 footprint and reflow soldering profiles specified in the datasheet. Confirm availability through authorized distributors.
Selection Notes
Select this component for space-constrained designs requiring a dual Schottky rectifier in a leadless package. The exposed cathode pad facilitates efficient heat dissipation, making it suitable for applications where thermal management is critical within a small footprint. Verify that the 40 V reverse voltage rating meets the circuit requirements and that the low forward voltage characteristics align with efficiency targets.
Part Context
This part belongs to the Nexperia PMEG4010 series of low VF dual Schottky barrier rectifiers. The series offers various package options including SOD323F and DFN2020D-3. The CPAS variant specifically utilizes the DFN2020D-3 package, distinguishing it from other series members like the CEJ or BEA which use different form factors. The product data sheet revision history indicates updates regarding automotive qualification status.
Replacement Considerations
PMEG4010CEJ: Similar electrical specifications but in SOD323F package. PMEG4010BEA: Similar electrical specifications but in SOD2 package. PMEG4010CPAS: Identical electrical specifications and package; verify if '-QX' suffix implies specific packaging or qualification differences.
