STF5N52K3-VB Product Introduction
STF5N52K3-VB is a unipolar N-channel power MOSFET in TO220F package with a drain-source withstand voltage (VDS) of 650V and a maximum drain current (ID) of 7A. This MOSFET uses Plannar technology and is suitable for applications with high voltage and medium current requirements. The turn-on voltage (Vth) is 3.5V, the maximum gate-source voltage is ±30V, and it can operate reliably over a wide voltage range. Its on-resistance (RDS(ON)) is 1100mΩ (at VGS = 10V), which is suitable for some medium-power applications with low on-resistance requirements. STF5N52K3-VB is particularly suitable for fields that require high voltage tolerance and a certain current carrying capacity.
