FDN304P Description

Short technical summary and product information.

The FDN304P from On Semiconductor is a P-Channel enhancement mode MOSFET designed for low-voltage power management and load switching applications. With a drain-source voltage (Vdss) of 20V and continuous drain current (Id) of 2.4A at 25°C, this device provides efficient switching performance in compact designs.

The MOSFET features a maximum on-resistance (Rds(on)) of 52mΩ at 4.5V gate drive and 2.4A drain current, enabling low conduction losses. Its gate threshold voltage (Vgs(th)) of 1.5V maximum at 250µA drain current supports logic-level gate drive operation. The device is housed in a surface-mount SOT-23-3 package, making it suitable for space-constrained PCB layouts.

Typical applications include battery management, power supply switching, and general-purpose load switching in portable electronics. The operating temperature range of -55°C to 150°C allows use in harsh environments. Input capacitance is 1312pF maximum at 10V, and gate charge is 20nC maximum at 4.5V, indicating moderate switching speeds optimized for low-frequency applications.
