FDN340P

FDN340P Description

The FDN340P from Fairchild (onsemi) is a P-Channel PowerTrench MOSFET designed for small-signal and power management applications. Encased in a compact SMD/SMT SSOT-3 package, it offers a 20V Drain-Source Breakdown Voltage (Vds) and a continuous drain current (Id) of 2A, making it suitable for low-voltage, high-efficiency circuits. With an Rds(on) of just 60 mΩ, this MOSFET minimizes conduction losses, enhancing energy efficiency in power-sensitive designs. Its enhancement-mode operation ensures reliable switching performance, while the PowerTrench technology provides superior thermal and electrical characteristics compared to conventional planar MOSFETs.
