C640 datasheet


This is 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.


Absolute maximum ratings ( Ta=25°C )

1. Collector to Base Voltage: Vcbo = 40 V

2. Collector to Emitter Voltage: Vceo = 30 V

3. Emitter to Base Voltage: Vebo = 5 V

4. Collector Current: Ic = 100 mA

5. Power Dissipation : Ptot =150 mW

6. Junction Temperature: Tj = 150°C

7. Storage Temperature: Tsg = -55 ~ +150°C
