K4A55DA-VB Product details
Back to previous pageProduct introduction：
**
K4A55DA-VB is a single N-channel power MOSFET in a TO220F package, designed for high voltage applications. The device has a drain-source voltage (VDS) of up to 650V, which can meet the working requirements of a variety of high-voltage environments. The threshold voltage (Vth) is 3.5V, ensuring smooth turn-on at a reasonable gate-source voltage. Although its on-resistance (RDS(ON)) is 2560mΩ at VGS=10V, it can still provide stable performance at a lower drain current (ID) of 4A. K4A55DA-VB uses traditional planar technology (Plannar) and is widely used in power management, industrial control, automotive electronics and other fields, providing reliable switching performance for circuits.
