• Collector-Base Voltage, max: 45 V
• Emitter-Base Voltage, max: 5 V
• Collector Current − Continuous, max: 0.5 A
• Collector Dissipation: 0.625 W
• DC Current Gain (h_fe): 40 to 250

The BC635 is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, collector, and base leads.
Here is an image showing the pin diagram of this transistor.The complementary PNP transistor to the BC635 is the BC636.You can replace the BC635 with the KSC1008C.
