The H945-P 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. The HS945-GR transistor (with suffix "C") is the center collector version of the H945-P.
Here is an image showing the pin diagram of this transistor.The H945-P transistor can have a current gain of 200 to 400. The gain of the H945 will be in the range from 90 to 600, for the H945-K it will be in the range from 300 to 600, for the H945-Q it will be in the range from 135 to 270, for the H945-R it will be in the range from 90 to 180.The complementary PNP transistor to the H945-P is the H733-P.The 2SC1623 (SOT-23), 2SC1623-L6 (SOT-23), 2SC2412 (SOT-23), 2SC2412-R (SOT-23), 2SC2712 (SOT-23), 2SC2712-GR (SOT-23), 2SC4116 (SOT-323), 2SC4116-GR (SOT-323), 2SC4738 (SOT-23), 2SC4738-GR (SOT-23), 2SD601A (SOT-23), FJX945 (SOT-323), FJX945G (SOT-323), KSC1623 (SOT-23), KSC1623-G (SOT-23), KTC3875 (SOT-23), KTC3875GL (SOT-23), KTC3875S (SOT-23), KTC3875S-GL (SOT-23) and MMBT2484 (SOT-23) is the SMD version of the H945-P transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SC945P is the TO-92 version of the H945-P.You can replace the H945-P with the 2N3417, 2SC1815, 2SC1815GR, 2SC2002, 2SC2002-K, 2SC2003, 2SC2003-K, 2SC2458, 2SC2458-GR, 2SC2960, 2SC3114, 2SC3114-T, 2SC3198, 2SC3198-GR, 2SC3199, 2SC3199-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, C1815, C1815GR, C945, C945GR, KSC1008C, KSC1008CG, KSC1815, KSC1815GR, KSC945C, KSC945CG, KSD1616, KSD1616-G, KSD1616A, KSD1616A-G, KTC1006, KTC3198, KTC3198GR, KTC3199, KTC3199GR or NTE192A.
