FDB44N25TM Description

Short technical summary and product information.

The FDB44N25TM is an N-Channel enhancement-mode power MOSFET manufactured by On Semiconductor. It is built with MOSFET (Metal Oxide) technology and is designed for high-efficiency power conversion applications.

 

Key electrical specifications include a drain-source voltage (Vdss) of 250V, a continuous drain current of 44A at case temperature (Tc), and a maximum drain-source on-resistance (Rds(on)) of 69mOhm at a gate voltage of 10V and drain current of 22A. The gate threshold voltage (Vgs(th)) is a maximum of 5V at 250µA, and the gate-source voltage rating is ±30V. The device offers a maximum gate charge (Qg) of 61nC at 10V, and an input capacitance (Ciss) of 2870pF at 25V drain-source voltage.

 

The MOSFET is rated for a maximum power dissipation of 307W at case temperature, and operates over a junction temperature range of -55°C to 150°C. It is suitable for switching and linear applications where high voltage and current handling are required.

 

The FDB44N25TM is offered in a surface-mount D2PAK (TO-263) package, which is also known as TO-263-3, D²Pak (2 Leads + Tab). This package provides good thermal and electrical performance for power management circuits.
