IXFN48N50 Description

Short technical summary and product information.

The IXFN48N50 is an N-channel MOSFET designed for high-voltage power switching applications. Manufactured by IXYS, this device is packaged in a SOT-227B (miniBLOC) chassis-mount module, enabling efficient thermal management in demanding environments.

 

Key electrical specifications include a drain-source voltage (Vdss) of 500V, a continuous drain current (Id) of 48A at case temperature, and a maximum drain-source on-resistance (Rds(on)) of 100mOhm when driven at 10V. The MOSFET can dissipate up to 520W of power and operates across a junction temperature range of -55°C to 150°C.

 

The gate charge is 270nC at 10V, and the input capacitance is 8400pF at 25V, making it suitable for moderate-frequency switching in power conversion circuits. The maximum gate threshold voltage is 4V at 8mA drain current.

 

The SOT-227-4 package (SOT-227B) offers a compact, four-pin design for chassis mounting, ideal for industrial power supplies, motor drives, and inverters. The device is marked as RoHS3 compliant, though this status is unverified.
