The 55 V Vdss rating sets the maximum rail voltage you can switch — fine for 12 V and 24 V systems, but tight for a 48 V bus with transients. The 110 A continuous current at 25°C is a case-temperature-limited number; real-world current will be lower unless you have a heatsink and airflow. The 8 mOhm Rds(on) at 10 V gate drive means low conduction losses at high current — expect about 0.88 W dissipation at 62 A, which is manageable with a decent heatsink. Gate charge of 146 nC at 10 V is moderate; the driver needs to source and sink that charge fast enough for your switching frequency. Input capacitance of 3247 pF at 25 V is typical for a TO-220-class die; it will load the gate driver, so check your drive strength if switching above 50 kHz. The IRF3205L is listed as obsolete.","metaTitle":"IRF3205L N-Channel MOSFET, 55V 110A, TO-262, Obsolete","metaDescription":"IRF3205L N-channel HEXFET MOSFET, 55V Vdss, 110A Id, 8mOhm Rds(on) at 10V.
