Product introduction：
Product Introduction: K2939L-VB MOSFET
K2939L-VB is a high-efficiency single N-channel power MOSFET designed in TO220 package, optimized for medium and high power applications. Its drain-source voltage (VDS) can reach up to 60V, and the drain current (ID) can reach 50A, suitable for a variety of load and power conditions. The device has a turn-on threshold voltage (Vth) of 1.7V, which enables fast turn-on at a lower gate voltage. Its on-resistance (RDS(ON)) is 24mΩ (at a gate voltage of 10V), showing excellent conduction performance, thereby reducing heat loss while improving system efficiency. These characteristics make the K2939L-VB very suitable for high-efficiency power management, switching power supplies and other related applications.
