MCH3484-VB MOSFET Product Introduction
The MCH3484-VB is a **single N-channel MOSFET** designed in **SC70-3** package, developed for high-efficiency switching and miniaturization applications. The device has a **20V** drain-source voltage (VDS), which can operate stably in a variety of low-voltage applications. Its gate-source voltage (VGS) range is **±12V**, ensuring that it can respond well under different operating conditions. The threshold voltage (Vth) of the MCH3484-VB is between **0.5V and 1.5V**, which enables it to turn on quickly at a lower gate voltage, suitable for fast switching applications.
In the on state, the MCH3484-VB exhibits excellent on-resistance (RDS(ON)), which is 48mΩ** at **2.5V, 40mΩ** at **4.5V, and 36mΩ** at **10V, which makes the device consume very little power under normal working conditions, especially suitable for low-power power management and switching applications. Its maximum drain current is **4A**, which can meet the needs of various applications. With the use of **Trench technology**, MCH3484-VB not only reduces the on-resistance, but also improves the thermal management performance, which is suitable for high-frequency switching and low-power circuits.
