FDBL0120N40 Description

Short technical summary and product information.

The FDBL0120N40 is an N-Channel power MOSFET from onsemi (formerly Fairchild Semiconductor) designed for high-current switching applications. It features a drain-source voltage rating of 40V and a continuous drain current of 240A (at case temperature Tc). The device achieves a low maximum on-resistance of only 1.2mOhm when driven with 10V at 80A.

 

This MOSFET incorporates metal-oxide semiconductor (MOSFET) technology and is intended for surface mount assembly. It comes in the 8-PowerSFN package (supplier device package 8-HPSOF). Key electrical characteristics include a gate charge of 107nC (max at 10V) and input capacitance of 7735pF (max at 25V drain-source), which influence switching behavior.

 

The device can dissipate up to 300W and operate over a junction temperature range of -55°C to +175°C. The maximum gate-source voltage is ±20V, with a gate threshold voltage of 4V at 250µA drain current. This part is RoHS3 compliant, REACH unaffected, and has an MSL rating of 1 (unlimited).
