The C945BL 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 C945BL transistor can have a current gain of 350 to 700. The gain of the C945 will be in the range from 70 to 700, for the C945GR it will be in the range from 200 to 400, for the C945O it will be in the range from 70 to 140, for the C945Y it will be in the range from 120 to 240.The complementary PNP transistor to the C945BL is the A733K.The 2SC2712 (SOT-23), 2SC2712-BL (SOT-23), 2SC4116 (SOT-323), 2SC4116-BL (SOT-323), 2SC4738 (SOT-23), 2SC4738-BL (SOT-23), FJX945 (SOT-323), FJX945L (SOT-323), KTC3875 (SOT-23), KTC3875BL (SOT-23), KTC3875S (SOT-23), KTC3875S-BL (SOT-23) and PMBT6428 (SOT-23) is the SMD version of the C945BL transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the C945BL with the 2SC1815, 2SC1815L, 2SC2458, 2SC2458-BL, 2SC3198, 2SC3198-BL, 2SC3199, 2SC3199-BL, 2SC3330, 2SC3331, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SD789, C1815, C1815BL, KSC1815, KSC1815L, KSC945C, KSC945CL, KTC1006, KTC3198, KTC3198BL, KTC3199 or KTC3199BL.
