The FDS9431A is a P-Channel PowerTrench MOSFET manufactured by onsemi. This device is designed for low-voltage power management applications and features a maximum drain-source voltage of 20V and a continuous drain current of 3.5A at 25°C. The MOSFET is specified at both 2.5V and 4.5V gate drive voltages, with a maximum on-resistance of 130mOhm at Vgs = 4.5V and 180mOhm at Vgs = 2.5V.
This device utilizes onsemi's high cell density DMOS technology to achieve low on-state resistance while maintaining fast switching performance. The maximum gate charge is 8.5nC at Vgs = 4.5V, and the input capacitance is 405pF at Vds = 10V. The gate threshold voltage is 1V maximum at Id = 250µA.
The FDS9431A is housed in an 8-SOIC surface mount package with a maximum power dissipation of 2.5W at 25°C. It is suitable for DC/DC converters, power management, load switching, and battery protection circuits. The operating junction temperature range is -55°C to 150°C.
