Product introduction：
1. STK0825-VB Product Introduction
STK0825-VB is a high-efficiency single N-channel MOSFET with a TO220 package, a drain-source voltage (VDS) of 250V and a maximum drain current (ID) of 14A. It uses Trench technology and has a lower on-resistance (RDS(ON) = 190mΩ@VGS=10V), which can significantly reduce switching losses and heat losses and improve working efficiency. The gate-source voltage (VGS) range of this MOSFET is ±20V, which is suitable for various standard drive circuit applications. The turn-on voltage (Vth) is 3.5V, which enables fast response in the control circuit. It is widely used in power management, switching power supplies, automotive electronics, home appliances, LED drivers and other fields, providing reliable and efficient power conversion and control.
