This document is a technical datasheet for the Toshiba 2SK2838, an enhancement-mode silicon N-channel MOS type field effect transistor. It is designed for high-speed, high-current switching applications such as chopper regulators, DC-DC converters, and motor drives.
The datasheet provides maximum ratings including a drain-source voltage of 400V and a continuous drain current of 55A. It details electrical characteristics like gate threshold voltage, on-resistance, and capacitance values at 25°C. Additionally, it includes graphical data for safe operating areas, transient thermal impedance, and switching performance curves.
| Drain-Source Voltage (Vdss) | 400 V |
|---|---|
