BUK138-50DL - Logic Level Power MOSFET for ECU Ignition Coil Drive Automotive Grade
Original BUK138-50DL - Logic Level Power MOSFET for Ignition Coil and Load Driving
The BUK138-50DL is a monolithic temperature and overload protected logic level power MOSFET. It is built using advanced TOPFET2 technology. This device is specifically designed for automotive ECU and engine control systems. It serves as a general-purpose switch for driving high-power loads reliably.
🔧 Engine Control Unit (ECU) Application
This power MOSFET is widely used on the backside of automotive ECUs. It is ideal for driving ignition coils, solenoids, motors, lamps, and heaters. The BUK138-50DL provides a simple and efficient way to control high-power loads with a low-current input signal. It ensures precise switching for critical engine management functions.
⚡ Automotive-Grade Reliability and Integrated Protection
Manufactured to meet rigorous automotive quality standards. The BUK138-50DL integrates complete fault protection on a single chip. It features current limiting, overload protection, overtemperature protection, and overvoltage clamping. These built-in safeguards prevent device damage under harsh conditions. This IC ensures long-term durability in engine control systems.
💡 Logic Level Gate Drive & Low On-Resistance
The device features a 5V logic compatible input level. It can be driven directly by a microcontroller without additional driver circuitry. This simplifies ECU board design and reduces component count. The low on-state resistance (Typ. 68mΩ) minimizes power dissipation and improves overall efficiency. Vertical power DMOS output stage delivers up to 8A continuous output current.
🌡️ Wide Operating Temperature Range
Reliable operation from -40°C to 150°C junction temperature. This ensures consistent performance in cold start conditions and high-load, high-heat environments. The monolithic protection trips automatically to keep the switch safe under all ambient temperature conditions.
🔌 DPAK Surface-Mount Package for Easy Integration
Housed in a standard DPAK (TO-252-3) surface-mount package. It is optimized for automated pick-and-place PCB assembly. This compact package saves precious board space while providing excellent thermal performance. The 3-pin design simplifies layout and reduces manufacturing costs.
