The KF4N20LW-RTK/HS is an N-channel MOSFET manufactured by KEC. It is designed for switching applications, power management, and motor control.

Applications

• Switching Regulators
• DC-DC Converters
• Power Management
• Motor Control
• LED Lighting

Features

• N-Channel MOSFET
• Low On-Resistance (RDS(on)): Reduces conduction losses.
• Fast Switching Speed: Enables high-frequency operation.
• Avalanche Ruggedness: Provides robustness against voltage transients.
• Lead-Free and RoHS Compliant: Environmentally friendly.

Benefits

• High Efficiency: Low on-resistance minimizes power dissipation.
• Reduced System Size: Fast switching speeds allow for smaller and lighter passive components.
• Improved Thermal Performance: Lower losses lead to reduced heat generation, improving system reliability.
• Enhanced Reliability: Avalanche ruggedness provides protection against voltage spikes and transients.

Specifications

The KF4N20LW-RTK/HS typically features a drain-source voltage (Vds) of 200V and a continuous drain current (Id) of 4A depending on the operating conditions. The on-resistance (Rds(on)) is very low, which minimizes conduction losses. Refer to the datasheet for complete specifications.
