K3991-ZK-VB MOSFET Product Introduction
K3991-ZK-VB is a high-efficiency N-channel MOSFET in TO252 package, designed for low voltage and high current applications. Its maximum drain-source voltage (VDS) is 30V, and the gate-source voltage (VGS) can reach ±20V. It has a very low on-resistance (RDS(ON)), which is 9mΩ at VGS of 4.5V and as low as 7mΩ at VGS of 10V. This enables the K3991-ZK-VB to carry currents of up to 70A, making it ideal for power management and drive applications that require high efficiency and low heat loss. The design based on Trench technology gives it excellent switching performance and extremely low switching losses, ensuring stable operation during fast switching operations.
