FDS8958A

FET, MOSFET Arrays Overview

The FDS8958A is a dual complementary N- and P-channel enhancement mode MOSFET manufactured by onsemi. It integrates two independent transistors within a single SOIC-8 surface-mount package. The N-channel device supports a drain-source voltage of 30 V with a continuous drain current of 7 A at 25°C, while the P-channel counterpart provides 30 V breakdown and 5 A continuous current. Both channels exhibit low on-resistance, specified at 28 mΩ for the N-channel and 52 mΩ for the P-channel at VGS = 10 V. The component operates across a temperature range of -55°C to +150°C junction temperature with a power dissipation rating of 2 W.
