IC/Component “BUK 7608” refers to a power MOSFET transistor, not a logic IC or microcontroller. Specifically:
🔌 What BUK7608 Is
BUK7608-55A (often shortened to BUK7608) is an N-channel power MOSFET (TrenchMOS FET) designed for high-current switching tasks in power electronics — especially in automotive and general power switching applications.
⚙️ Key Technical Details

Continuous Drain Current: ~75 A (at 25 °C)
Package: D2PAK / TO-263 surface-mount
Low On-Resistance: ~8 mΩ @ V<sub>GS</sub> = 10 V
Automotive-Qualified: AEC-Q101 compliant (means it is suitable for automotive electronics)
Operating Temp: About –55 °C to +175 °C
Typical Use: Power switching loads, motors, solenoids, lamps, automotive systems etc.
🔋 What It Does
A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) like the BUK7608 is used as an electronic switch that can turn high currents on and off efficiently. It’s often used in:
Automotive power modules (e.g., for lights, motors, fans) 🚗
DC-DC converters and power regulation circuits 🔌
General purpose high-current switching in industrial electronics 🔧
📍 In Simple Terms
The BUK7608 isn’t a typical logic IC — it’s a power transistor (MOSFET) used to control large currents and voltages efficiently. It’s equivalent to a high-power electronic switch that can handle around 75 A of current and about 55 V.
If you’re replacing it on a board, make sure the voltage/current ratings and package (D2PAK) match the original device — that’s crucial for proper operation.
