BUK138-50DL is a logic level power MOSFET with overload protection, suitable for general purpose switch applications such as driving lamps, motors, solenoids, and heaters in automotive systems.
This document is a product specification datasheet for the Philips BUK138-50DL, a monolithic temperature and overload protected logic level power MOSFET. The device utilizes TOPFET technology and is housed in a 3-pin surface mount plastic package (SOT428), which is the D-PAK version of the BUK117-50DL.
| Continuous drain source voltage | 50 V |
|---|---|
| Total power dissipation (Ta<=25°C) | 40 W |
| Continuous junction temperature | 150 °C |
It is used as a general purpose switch for driving lamps, motors, solenoids, and heaters.
The power MOSFET actively turns on to clamp overvoltage transients.
