PD - 91545A POWER MOSFET SURFACE MOUNT(SMD-1) IRFN044 60V, N-CHANNEL ® HEXFET MOSFET TECHNOLOGY Product Summary Part Number IRFN044 R DS(on) 0.04 Ω ID 44A HEXFET® MOSFET technology is the key to International Rectifier’s advanced line of power MOSFET transistors. The efficient geometry design achieves very low on-state resistance combined with high transconductance. HEXFET transistors also feature all of the well-established advantages of MOSFETs, such as voltage control, very fast switching, ease of paralleling and electrical parameter temperature stability. They are well-suited for applications such as switching power supplies, motor controls, inverters, choppers, audio amplifiers, high energy pulse circuits, and virtually any application where high reliability is required. The HEXFET transistor’s totally isolated package eliminates the need for additional isolating material between the device and the heatsink. This improves thermal efficiency and reduces drain capacitance.
