The IRFZ44NPBF is a HEXFET Power MOSFET from Infineon Technologies (formerly International Rectifier). It is designed for high efficiency and fast switching applications. With a drain-source voltage rating of 55V and a continuous drain current of 49A at 25°C, it is suitable for medium-power switching and amplification circuits. The on-resistance is typically 17.5mOhm at 25A and 10V gate drive, ensuring low conduction losses. The device is fully avalanche rated and features a junction temperature range of -55°C to 175°C. It is housed in the industry-standard TO-220AB through-hole package, which offers low thermal resistance (1.5°C/W junction-to-case) and easy mounting. The TO-220 package is suitable for power dissipation up to 94W. The device is also lead-free and RoHS compliant (datasheet indicates lead-free). Key electrical characteristics include a total gate charge of 63nC, input capacitance of 1470pF, and fast switching times (ton=12ns, tr=60ns, toff=44ns, tf=45ns).
