ST 2SC640
NPN Silicon Epitaxial Planar Transistor
for switching and AF amplifier applications.
The transistor is subdivided into five groups R, O, Y,
P and L, according to its DC current gain. As
complementary type the PNP transistor ST 2SA733
is recommended.
On special request, these transistors can be
manufactured in different pin configurations.
