Description TO-220
This Power MOSFET series realized with
STMicroelectronics unique STripFET process has
specifically been designed to minimize input
capacitance and gate charge. It is therefore Internal schematic diagram
suitable as primary switch in advanced high-
efficiency isolated DC-DC converters for Telecom
and Computer application. It is also intended for
any application with low gate charge drive
requirements.
