FDW2520C

FET, MOSFET Arrays Overview

The FDW2520C is a complementary PowerTrench MOSFET array manufactured by onsemi, originally developed by Fairchild Semiconductor. It integrates an N-channel and a P-channel device within a single low-profile TSSOP-8 package. The N-channel transistor (Q1) supports a continuous drain current of 6 A with a maximum drain-source voltage of 20 V and an on-resistance of 18 mΩ at VGS = 4.5 V. The P-channel transistor (Q2) provides a continuous drain current of -4.4 A, maintaining the same 20 V rating and achieving an on-resistance of 35 mΩ at VGS = -4.5 V. The component operates across a junction temperature range of -55°C to +150°C.
