The 2SC945P 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 2SC945P transistor can have a current gain of 200 to 400. The gain of the 2SC945 will be in the range from 90 to 600, for the 2SC945K it will be in the range from 300 to 600, for the 2SC945Q it will be in the range from 135 to 270, for the 2SC945R it will be in the range from 90 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SC945P might only be marked "C945P".The complementary PNP transistor to the 2SC945P is the 2SA733P.The 2SC1623 (SOT-23), 2SC1623-L6 (SOT-23), 2SD601A (SOT-23), KSC1623 (SOT-23), KSC1623-G (SOT-23) and MMBT2484 (SOT-23) is the SMD version of the 2SC945P transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The H945-P, HS945-GR, KSC945Y is the TO-92 version of the 2SC945P.You can replace the 2SC945P with the 2N3417, 2SC1570, 2SC1815, 2SC1815GR, 2SC1843, 2SC1843P, 2SC1844, 2SC1844P, 2SC2002, 2SC2002-K, 2SC2003, 2SC2003-K, 2SC2458, 2SC2458-GR, 2SC2634, 2SC2785, 2SC2960, 2SC3114, 2SC3114-T, 2SC3198, 2SC3198-GR, 2SC3199, 2SC3199-GR, 2SC3329, 2SC3329-GR, 2SC3330, 2SC3330-T, 2SC3331, 2SC3331-T, 2SC3382, 2SC3382-T, 2SC3383, 2SC3383-T, 2SC3708, 2SC3708-T, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SC4408, 2SC4604, 2SC536N, 2SC6043, 2SD1207, 2SD1207-T, 2SD1347, 2SD1347T, 2SD1616, 2SD1616-K, 2SD1616A, 2SD1616A-K, 2SD1835, 2SD1835-T, 2SD438, 2SD789, BC182L, BC182LB, C1815, C1815GR, C945, C945GR, H945, H945-P, KSC1008C, KSC1008CG, KSC1815, KSC1815GR, KSC945C, KSC945CG, KSD1616, KSD1616-G, KSD1616A, KSD1616A-G, KTC1006, KTC3198, KTC3198GR, KTC3199, KTC3199GR or NTE192A.
