?The Fir4N60FG is a MOSFET N-Trench 600V 4A (Tc) 4V @ 250uA 2.4 O @ 2A, 10V TO-220F (TO-220IS) RoHS manufactured by First Semicon. It is a low-barrier N-channel power MOSFET designed to operate in high voltage and current applications. It features a low threshold voltage, a low on-state resistance, and a high breakdown voltage. This makes it suitable for use in a range of high-frequency, high-efficiency circuits such as DC-DC converters, motor control applications, and pulse-width modulation circuits. The TO-220IS package with full isolation and flangeless mounting enables efficient power dissipation. Additionally, this part is RoHS compliant, ensuring that it is free from hazardous substances.
