The BS250 is a TO-92 -packaged P Channel enhancement-mode vertical D-MOS transistor. The transistor's pin configuration is as follows: The Source pin is the first, the Gate pin is the second, and the Drain pin is the third.
The transistor's highest drain to source voltage is -45V; its continuous drain current is -0.25A or -250mA; its gate-source voltage is 20V, and its maximum power dissipation is 8300mW.
Because of its various characteristics, such as low threshold voltage, quick switching speed, and low on-resistance, the transistor can be utilized in a wide range of applications, including as a driver for relays, displays, memories, driving other transistors, and motor controllers. It's also suitable for a wide range of power supply applications. In addition, it will work well in low-voltage and battery-powered applications.
