FDB031N08 Description

Short technical summary and product information.

The FDB031N08 is an N-Channel power MOSFET manufactured by ON Semiconductor, designed for high-efficiency power switching applications. It features a drain-to-source voltage (Vdss) of 75V and a continuous drain current (Id) of 120A at case temperature Tc. The device achieves a low maximum on-state resistance (Rds(on)) of 3.1 mOhm at Vgs = 10V and Id = 75A, minimizing conduction losses.

 

The MOSFET utilizes standard MOSFET (Metal Oxide) technology and offers a maximum power dissipation of 375W at Tc. It supports a maximum gate threshold voltage (Vgs(th)) of 4.5V and a maximum gate charge (Qg) of 220 nC at Vgs = 10V, indicating moderate switching speed. Input capacitance (Ciss) is typically 15160 pF at Vds = 25V.

 

The device is housed in a D²PAK (TO-263) surface mount package with three leads and a tab for heat sinking. It operates over a junction temperature range of -55°C to 175°C, suitable for demanding industrial environments. The part is RoHS3 compliant and MSL 1 rated.
