DESCRIPTION
The 2SK4147 is a switching element that is most suitable for use in DC-DC converter whose DC input voltage is 24 to 48 V. Having low on-resistance, excelling in the switching characteristics, and providing the small surface mounting outline, the 2SK4147 is ideal for use in high-speed switching of the devices on which space-saving and automation of mounting are promoted.
