Now in Stock: BUK114-50L – Brand New, Fully Traceable, and Ready to Ship!

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.
