The BUK100-50GS TOPFET is a temperature and overload protected power MOSFET for automotive systems and other applications.
The document describes the Philips BUK100-50GS, a PowerMOS transistor featuring a vertical DMOS output stage. It is designed as a general-purpose switch for automotive applications such as driving lamps, motors, solenoids, and heaters. The device includes built-in protection features against over temperature, short circuit loads, and overvoltage transients.
| Continuous drain source voltage | 50 V |
|---|---|
| Continuous drain current (25°C) | 15 A |
| Total power dissipation | 40 W |
| Continuous junction temperature | 150 °C |
| Drain-source on-state resistance | 100 mΩ |
The device supports a continuous drain current of up to 15 A when the junction temperature is 25 °C.
The transistor can dissipate a maximum of 40 W when the case temperature does not exceed 25 °C.
The device triggers its over-temperature protection when the internal junction reaches 150 °C.
The allowable continuous drain current drops to 9.5 A when the case temperature reaches 100 °C.
