IRF640NLPBF N-Channel Power MOSFET
The IRF640NLPBF is a high-performance, fifth-generation HEXFET® N-channel power MOSFET from Infineon Technologies (formerly International Rectifier), engineered for efficient power switching applications. Built on advanced PD-95046 process technology, this device delivers an optimal balance of low conduction losses, fast switching speed, and robust ruggedness. It is rated for a 200V drain-source voltage (VDS) and can handle a continuous drain current (ID) of 18A at 25°C, with a maximum power dissipation of 150W. Featuring a typical on-resistance (RDS(on)) of just 0.15Ω at 10V gate drive, it minimizes power loss during conduction. The MOSFET is fully avalanche rated and offers exceptional dynamic dv/dt capability, ensuring reliable operation in inductive load switching. Housed in a through-hole TO-262 package for efficient thermal dissipation, it operates over a wide junction temperature range of -55°C to +175°C.
