K2549-VB Product details
Back to previous pageProduct introduction：
Product Introduction:
K2549-VB is a single N-channel MOSFET based on Trench technology, packaged in SOT89. It is designed for low-voltage applications, with a maximum drain-source voltage (VDS) of 30V, a gate-source voltage (VGS) of ±20V, and an on-resistance (RDS(ON)) of 30mΩ and 22mΩ at VGS = 2.5V and VGS = 4.5V, respectively. It can carry a drain current of up to 6.8A and is very suitable for low-voltage switching and power management applications. The use of Trench technology gives it lower on-resistance and higher efficiency, making it particularly suitable for portable devices and power management modules.
