BUK7840-55-VB MOSFET Product Introduction



BUK7840-55-VB is a high-performance single N-channel power MOSFET in SOT223 package, designed for medium and low voltage applications. With a drain-source voltage (VDS) of 60V and a gate-source voltage (VGS) range of ±20V, this MOSFET can operate stably over a wide voltage range. Its threshold voltage (Vth) is 1.7V, ensuring reliable conduction even at lower gate voltages. The on-resistance (RDS(ON)) of BUK7840-55-VB is 33mΩ @ VGS=4.5V and 28mΩ @ VGS=10V, supporting a maximum continuous drain current (ID) of 7A. Using Trench technology, it provides low on-resistance and excellent switching performance, suitable for medium and low power and high-efficiency application scenarios.
