SEMTECH_ELEC ST2SC1923

ST 2SC1923
NPN Silicon Epitaxial Planar Transistor
for high frequency amplifier applications
FM, RF, MIX, IF amplifier applications.
The transistor is subdivided into three groups, R, O
and Y, according to its DC current gain.
On special request, these transistors can be
manufactured in different pin configurations.
