Product introduction：
Product Introduction: MMFTN138-VB MOSFET
MMFTN138-VB is a single N-channel MOSFET in a SOT23-3 package, designed for low voltage and low current applications. The maximum drain-source voltage (VDS) of this MOSFET is 60V, and it supports a maximum gate-source voltage (VGS) of ±20V, which is suitable for various switching and control circuits. Its threshold voltage (Vth) is 1.7V, which enables effective switching at lower voltages. In addition, based on **Trench technology**, MMFTN138-VB has a higher on-resistance (RDS(ON)) of 3100mΩ and 2800mΩ at gate voltages of 4.5V and 10V, respectively, which is suitable for applications in low-power devices, ensuring high efficiency and reliability.
