FDS6982S

FET, MOSFET Arrays Overview

The FDS6982S is a dual N-channel PowerTrench SyncFET designed for synchronous DC/DC power supplies in notebook computers and battery-powered devices. It integrates two unique MOSFETs: Q1 optimized for low switching losses with a typical gate charge of 8.5 nC, and Q2 optimized for conduction losses featuring an integrated Schottky diode. The device operates at 30V with continuous drain currents of 6.3A (Q1) and 8.6A (Q2). Key electrical parameters include RDS(on) values of 0.028Ω (Q1) and 0.016Ω (Q2) at VGS=10V. It utilizes an SO-8 surface mount package with a junction temperature range of -55°C to +150°C.
