The BUK114-50L from NXP Semiconductors (originally Philips) is a logic-level N-channel power MOSFET designed for automotive and industrial switching applications. Housed in a compact 5-pin D²PAK (SOT-426) surface-mount package, it combines high efficiency, low on-resistance, and built-in protection for reliable operation in demanding environments. 

This device is part of NXP’s TOPFET family, integrating a vertical DMOS power stage with temperature and short-circuit protection features. With a 50 V drain-source voltage, 15 A continuous drain current, and low RDS(on) of 100 mΩ (typ.), it delivers strong, consistent performance in applications such as lamp drivers, solenoids, and DC motors. 

Let’s take a closer look at what makes this automotive-grade transistor a dependable choice for power switching. 

## **Key Features of the BUK114-50L** 

**Logic-Level N-Channel MOSFET**   
Operates directly from 5 V logic inputs for easy control and integration with microcontrollers. 

**Integrated Overload Protection**   
Built-in safeguards against over-temperature and short-circuit conditions with automatic shutdown and latch-off reset. 

**Overvoltage Clamping**   
Active clamping at 50–65 V protects against inductive load transients during turn-off. 

**Low On-Resistance**   
Typical RDS (on) of 100 mΩ (VIS = 7 V) minimises power loss and heat generation. 

**Thermal and Short-Circuit Resilience**   
Capable of handling up to 0.8 kW instantaneous overload dissipation and 200 mJ inductive energy without failure. 

**Built-In Flag Pin for Status Monitoring**   
Provides fault indication (over-temperature, short-circuit, or supply fault) for intelligent system feedback. 

**Fast Switching Performance**   
Turn-on delay of 8 ns, rise time of 13 ns, and turn-off delay of 100 ns ensure rapid response in PWM or automotive systems. 

**Compact D²PAK Surface-Mount Package**   
Space-efficient SOT-426 (5-pin) format with excellent heat transfer and Rth(j-mb) ≤ 3 K/W. 

## **Applications of the ****BUK114-50L**
