F25NM50N (ST) / STx25NM50N / STF25NM50N / 25N50 (SH) Mosfet Transistor (SH) TO-220F Code: 93028174

The F25NM50N (commonly part of the STx25NM50N / STF25NM50N family by STMicroelectronics) is an N-channel power MOSFET built using second-generation MDmesh technology, featuring a 500V drain-source breakdown voltage, a 22A continuous drain current, and a low on-resistance of approximately 0.11 ohms.

Key Specifications

• Drain-Source Voltage :500V (up to 550V at maximum junction temperature)
• Continuous Drain Current :22A
• Drain-Source On-Resistance :Max 0.14 ohms (typ. 0.11 ohms)
• Gate-Source Voltage :± 25V
• Maximum Power Dissipation :40W (for fully isolated packages like TO-220FP)
• Technology:MDmesh II (yielding low gate charge and fast switching speeds)

Package & Applications

• Package Types:Available in TO-220, TO-220FP, I²PAK, D²PAK, and TO-247 (F25NM50N usually denotes the fully molded TO-220FP version).

Target Uses: High-efficiency switch-mode power supplies, high-frequency DC-DC converters (boost/buck topologies), and power factor correction (PFC) inverters. Note that this specific series is designated as mature or end-of-life by primary manufacturers.
