Power MOSFET Vishay IRFL110 (MPN IRFL110TRPBF)

Vishay IRFL110 is an N-channel power MOSFET designed for switching and power-management applications. Supplied in a surface-mount SOT-223 package and available in tape and reel, this device is intended for use where a discrete power transistor is required. The MOSFET is appropriate for converter stages, motor driver circuits and power-supply stages that need controlled switching and thermal-aware layout. The device documentation lists a dynamic dV/dt rating, making it suitable for applications with fast voltage transitions.

Advantages

The SOT-223 surface-mount package provides a compact footprint with straightforward PCB mounting for automated assembly. Availability in tape and reel supports high-volume pick-and-place manufacturing. The dynamic dV/dt rating helps ensure reliable switching during rapid voltage changes, while the discrete N-channel design allows integration into a variety of power topologies without requiring integrated driver modules.

Suitable for

• Load switching in power-supply rails
• DC–DC converter stages
• Motor driver low-side or high-side switching (with appropriate gate drive)
• Thermally constrained power circuits and board-level power management

Key specifications

• Device type: N-channel power MOSFET
• Package: SOT-223 surface-mount
• Mounting: Surface-mount, tape-and-reel availability
• Dynamic characteristic: dV/dt rating for fast voltage transitions

How to use

Integrate the IRFL110 as a discrete switching element on the PCB, observing the device’s recommended pad layout for SOT-223 to ensure adequate thermal conduction and solder fillet formation. Use appropriate gate drive levels consistent with the MOSFET’s threshold and on-resistance characteristics as specified in the manufacturer datasheet. Include proper thermal vias or heat-spreading copper where necessary for power-dissipation. Follow standard precautions for ESD-sensitive MOSFETs during handling and assembly.

Usage recommendations

Consult the Vishay datasheet for absolute maximum ratings, detailed electrical characteristics and thermal information before finalizing the circuit. Validate gate-drive timing and snubbing or clamping measures in designs that experience high dV/dt to prevent undesired switching or device stress.
