FDQ7238AS - N-Channel MOSFET

Description

The FDQ7238AS is designed to replace two single SO8 MOSFETs in DC to DC power supplies.

The high-side switch (Q1) is designed with specific emphasis on reducing switching losses while the low-side switch (Q2) is optimized to reduce conduction losses using Fairchild’s SyncFET TM technology.

Features

  • Q2: 14 A, 30V. RDS(on) = 8.7 mΩ @ VGS = 10V RDS(on) = 10.5 mΩ @ VGS = 4.5V.
  • Q1: 11 A, 30V. RDS(on) = 13.2 mΩ @ VGS = 10V RDS(on) = 16 mΩ @ VGS = 4.5V SO-14 pin 1 S2 S2 S2 G1G2 Vin Absolute Maximum Ratings TA = 25°C unless otherwise noted Symbol VDSS VGSS ID PD TJ, TSTG Parameter Drain-Source Voltage Gate-Source Voltage Drain Current - Continuous - Pulsed Power Dissipation for Single Operation (Note 1a) (Note 1a & 1b) (Note 1c & 1d) Operating and Storage Junction Temper.
