Product introduction：
UF740L-TA3-T-VB is a single N-channel power MOSFET in a TO220 package with a 650V withstand voltage capability, suitable for high-voltage applications. The device has a high drain-source voltage (VDS 650V) and supports a gate voltage of up to 30V (VGS ±30V). Its typical turn-on voltage threshold is 3.5V, which ensures good switching performance. RDS(ON) is 500mΩ at VGS=10V, which means low conduction losses under normal operating conditions and can provide a maximum leakage current (ID) of 9A. The use of SJ_Multi-EPI technology improves the efficiency and reliability of this MOSFET, making it particularly suitable for high-frequency switching applications, power conversion, and a variety of devices in the field of power electronics.
