BSS138 Datasheet – Vdss=50V, N-ch, MOSFET – Fairchild

Part Number : BSS138, Marking : SS

Function : N-Channel Logic Level Enhancement Mode Field Effect Transistor

Package : SOT-23 Package

Manufactures : Fairchild Semiconductor




This N-Channel enhancement mode field effect transistor is produced using Fairchild’s proprietary, high cell density, DMOS technology. This product has been designed to minimize on-state resistance while providing rugged, reliable, and fast switching performance. The BSS138 is particularly suited for low voltage, low current applications such as small servo motor control, power MOSFET gate drivers, and other switching applications.
