Overview
The BSS123L is an N-channel logic level enhancement mode field effect transistor (FET) produced by onsemi. This transistor is manufactured using high cell density, trench MOSFET technology, which minimizes on-state resistance and provides rugged, reliable, and fast switching performance. It is particularly suited for low-voltage, low-current applications and is available in a compact SOT-23 surface mount package. The device is Pb-free and halogen-free, making it compliant with RoHS standards.
