BUK108-50GS is a power MOSFET from Philips Semiconductors. It is mainly used in automotive systems and other applications. Its features include low on-state resistance, over temperature protection, and short circuit protection.
The BUK108-50GS is a PowerMOS transistor featuring a vertical power DMOS output stage, designed as a general-purpose switch for automotive systems and other applications. It includes built-in protection against over temperature, short circuit loads, and overvoltage transients, with a reset capability via the input pin.
The device is housed in a 3-pin plastic surface mount envelope (SOT404) and is intended for driving lamps, motors, solenoids, and heaters. Key specifications include a continuous drain-source voltage of 50 V, a continuous drain current of 15 A, and a total power dissipation of 40 W.
| Continuous drain-source voltage | 50 V |
|---|---|
| Continuous drain current | 15 A |
| Total power dissipation | 40 W |
| Continuous junction temperature | 150 °C |
| Drain-source on-state resistance | 100 mQ |
| Package type | SOT404 |
The device remains latched off until it is reset by the input pin.
The typical input threshold voltage is 1.5 V when Vos is 5 V and Ib is 1 mA.
