Description

General part information

BSS138_F085 Series

These N-Channel enhancement mode field effect tran sistors are produced using ON Semiconductor’s proprietary, high cell density, DMOS technology. These products have been designed to minimize on-state resistance while pro vide rugged, reliable, and fast switching perfor mance.These products are particularly suited for low voltage, low current applications such as small servo motor control, power MOSFET gate drivers, and otherswitching applications.
