The STF15N95K5 from STMicroelectronics is a high-voltage MDmesh K5 N-channel power MOSFET featuring a 950V drain-source breakdown voltage, a continuous drain current of 12A at a 25°C case temperature, and a pulsed drain current of up to 48A. Its proprietary vertical structure is designed to reduce on-resistance and gate charge for high-efficiency, high-power-density switching applications.
At VGS=10V and ID=6A, the device has a typical drain-source on-resistance of 410mΩ and a maximum value of 500mΩ. Typical total gate charge is 30nC, including 5nC gate-source charge and 22nC gate-drain charge, helping reduce gate-drive losses in switching converters. Its gate-threshold voltage ranges from 3V to 5V.
The STF15N95K5 is supplied in a fully insulated TO-220FP through-hole package with a maximum power dissipation of 30W, junction-to-case thermal resistance of 4.2°C/W, and 2.5kVrms insulation withstand voltage. It supports a junction-temperature range of -55°C to +150°C and features gate Zener protection, 100% avalanche testing, and a single-pulse avalanche-energy rating of 124mJ.
The device is supplied in tube packaging and is classified as an industrial-grade ECOPACK2 component. It is suitable for high-voltage power conversion, AC/DC and DC/DC supplies, power-factor-correction stages, adapters, and general power-switching circuits. Switching frequency, gate drive, thermal design, and safe operating area should be verified in the final application.
