FQA44N30 Description

Short technical summary and product information.

The FQA44N30 is an N-Channel MOSFET from ON Semiconductor designed for high-power switching applications. It features a maximum drain-source voltage (Vdss) of 300V and a continuous drain current (Id) of 43.5A at case temperature (Tc). The on-resistance (Rds(on)) is typically 69mOhm at a drain current of 21.75A and gate-source voltage of 10V. The gate threshold voltage (Vgs(th)) is 5V maximum at 250µA drain current. Total gate charge (Qg) is 150nC at Vgs=10V, and input capacitance (Ciss) is 5600pF at Vds=25V. The device can dissipate up to 310W at Tc and operates over a junction temperature range of -55°C to 150°C. It is offered in a through-hole TO-3P-3 / SC-65-3 package with a supplier device package of TO-3PN. The component is listed as RoHS3 compliant (unverified).
