FDQ7238AS Description

Short technical summary and product information.

The FDQ7238AS is a dual N-Channel PowerTrench MOSFET designed to replace two single SO-8 MOSFETs in DC to DC power supplies. The high-side switch (Q1) is optimized for reducing switching losses while the low-side switch (Q2) is optimized to reduce conduction losses using Fairchild's SyncFET technology. It includes a patented combination of a MOSFET monolithically integrated with a Schottky diode.

 

Key electrical specifications include a drain-source voltage of 30V for both MOSFETs. Q2 supports a continuous drain current of 14A with a typical on-resistance of 8.7 mOhm at VGS=10V, while Q1 supports 11A with a typical on-resistance of 13.2 mOhm at VGS=10V. Both devices feature logic level gate drive and a gate threshold voltage range of 1V to 3V.

 

The device is housed in a 14-SOIC (0.154", 3.90mm Width) surface mount package. It operates over a junction temperature range of -55°C to 150°C. Power dissipation depends on mounting conditions, with Q2 rated up to 2.4W and Q1 up to 1.8W under certain conditions. Thermal resistance junction-to-ambient ranges from 52°C/W to 118°C/W depending on the MOSFET and mounting notes.
