Back to previous pageProduct introduction：
1. Product Introduction
K2978-VB is a high-efficiency N-channel MOSFET in SOT89 package, designed for low voltage and medium current applications. With a drain-source voltage (VDS) of 30V and a maximum gate voltage (VGS) of ±20V, the device is suitable for a variety of power management and switching applications. The threshold voltage of K2978-VB is 1.7V, enabling it to turn on quickly at a lower gate voltage. Its on-resistance performs well at different gate voltages, at 30mΩ (@VGS=2.5V) and 22mΩ (@VGS=4.5V), respectively, and the maximum drain current can reach 6.8A. Using Trench technology, K2978-VB has significant advantages in both power consumption and switching efficiency, and is suitable for the needs of various modern electronic devices.
