FDD4243 Description

Short technical summary and product information.

The FDD4243 is a P-Channel power MOSFET manufactured by On Semiconductor. It is designed for load switching and power management applications requiring a high-performance P-Channel device.

 

Key electrical specifications include a drain-to-source voltage (Vdss) of 40V, continuous drain current of 6.7A at ambient temperature (Ta) and 14A at case temperature (Tc). The maximum on-resistance (Rds(on)) is 44mOhm at a gate drive of 10V, with a gate threshold voltage of 3V maximum. The device features a maximum gate charge of 29nC and input capacitance of 1550pF.

 

The FDD4243 is offered in a surface-mount DPAK (TO-252) package, supporting efficient heat dissipation with a maximum power dissipation of 42W at case temperature. The operating junction temperature range is -55°C to 150°C.
