SEMTECH_ELEC ST28S

ST 28S
NPN Silicon Epitaxial Planar Transistor
for switching and amplifier applications. Especially
suitable for AF-driver stages and low power output
stages.
The transistor is subdivided into one group, according
to its DC current gain.
On special request, these transistors can be
manufactured in different pin configurations.
