FS821-VB Product Introduction
FS821-VB is a high voltage N-Channel MOSFET in TO220F package, designed for high voltage and medium current applications. It uses Plannar technology and is suitable for electronic systems that require high voltage tolerance. The maximum drain-source voltage (VDS) of this MOSFET is 650V, and the gate-source voltage (VGS) allowable range is ±30V. Its gate threshold voltage (Vth) is 3.5V, which can be turned on at a lower gate voltage. The on-resistance (RDS(ON)) of FS821-VB is 2560mΩ@VGS=10V, and it supports a maximum drain current (ID) of 4A. Despite its relatively high on-resistance, it can still provide stable performance in a high voltage environment.
