Product Introduction
**K1228-VB** is a small N-channel MOSFET in a SOT23-3 package, designed for low voltage and low current applications. The device has a maximum drain-source voltage (VDS) of 60V and a gate-source voltage (VGS) that can withstand ±20V, making it suitable for a variety of power management and signal amplification applications. The threshold voltage (Vth) of K1228-VB is 1.7V, ensuring good switching performance at low voltage. At VGS = 4.5V, the on-resistance (RDS(ON)) reaches 3100mΩ, and decreases to 2800mΩ at VGS = 10V, providing reasonable conduction characteristics, suitable for electronic devices that require high-frequency switching and low power consumption.
