The FDR838P is a P-Channel MOSFET manufactured using Fairchild Semiconductor's advanced PowerTrench process, now part of On Semiconductor's portfolio. It is designed for load switch, motor driving, and power management applications. The device is rated for a maximum drain-source voltage of -20V and a continuous drain current of -8A at 25°C ambient temperature. It offers a maximum on-resistance of 17mOhm at Vgs = -4.5V and 24mOhm at Vgs = -2.5V, with typical values of 14mOhm and 20mOhm respectively. The gate threshold voltage ranges from 0.4V to 1.5V, with a typical value of 0.85V. Total gate charge is typically 30nC and maximum 45nC at Vgs = 4.5V. Input capacitance is typically 3300pF, output capacitance 730pF, and reverse transfer capacitance 350pF. The device is housed in a SuperSOT-8 surface mount package (8-LSOP, 3.30mm width), which is 38% smaller than a standard SO-8 with a low profile of 1mm thickness. Power dissipation is 1.8W at 25°C ambient, with a junction-to-ambient thermal resistance of 70°C/W. Operating junction temperature range is -55°C to 150°C. The device is supplied on 13-inch reels with 12mm tape width, in quantities of 3000 units.
