The product is a BUK104-50L/S type PowerMOS transistor produced by Philips Semiconductors, which has a 5V logic compatible input level and a 15 A continuous drain current
This document is a product specification for the PowerMOS transistor BUK104-50L/S (and variants BUK104-50LP/SP), described as a logic level TOPFET. It features low on-state resistance, overload protection against over temperature and short circuit loads, and ESD protection. The device is packaged in a 5-pin plastic envelope intended for automotive systems and other applications such as driving lamps, motors, solenoids, heaters, and general controllers.
| Continuous drain source voltage (VDS) | 50 V |
|---|---|
| Continuous drain current (ID) at Tmb ≤ 25 °C | 15 A |
| Continuous junction temperature (Tj) | 150 °C |
| Protection supply voltage (VPSN) for BUK104-50L | 5 V |
Yes, it includes overload protection against over temperature and short circuit loads.
The device supports a maximum continuous drain current of 15 A at an ambient temperature of 25 °C, with a total power dissipation limit of 40 W.
The continuous junction temperature must not exceed 150 °C under normal operating conditions.
When the drain-source voltage exceeds 50 V, the power MOSFET actively turns on to clamp the voltage.
