Overview
The CMLM0574 TR PBFREE is a surface mount module integrating an N-Channel MOSFET and a Schottky diode. The MOSFET provides a drain-source voltage of 30 V with a continuous drain current of 450 mA at ambient temperature. It dissipates 350 mW of power under the same conditions. The integrated Schottky diode offers a reverse voltage rating of 40 V and supports a forward current of 500 mA. This combination is designed for compact high-current applications requiring efficient switching and rectification in a single package.
Feature Summary
- Integrates an N-Channel MOSFET and a low forward voltage Schottky diode in a single surface mount module
- Designed for high current and fast switching applications
- Suitable for power factor correction and lighting circuits
Applications
- Power Factor Correction (PFC) circuits
- Lighting systems
- High voltage fast switching applications
Procurement Notes
Verify the specific ordering suffix to ensure compliance with lead-free plating requirements, as indicated by the PBFREE designation in the part number. Confirm the tape and reel packaging configuration matches the TR suffix. Cross-reference the exact electrical parameters with the official Central Semiconductor datasheet before integration, as specifications may vary by revision or manufacturing batch.
Selection Notes
Select this component when space constraints require combining a switch and a freewheeling diode. Ensure the 30 V MOSFET rating exceeds the circuit's maximum operating voltage. Verify that the 450 mA MOSFET current and 500 mA diode current meet the load requirements. Consider the thermal dissipation capabilities relative to the PCB layout and ambient temperature conditions.
