BSS123 3D Model
The BSS123 is a compact Logic Level N-Channel MOSFET. The MOSFET has a very low threshold voltage of 01.7V and hence can be used with any low voltage application circuits and for level shifting applications. Adding to this the Mosfet also has low on-state resistance and low input capacitance which makes it efficient in switching circuits since it requires only less gate current even when switching at high speeds.
