Here is an image showing the pin diagram of this transistor.The 2SC3180 transistor can have a current gain of 55 to 160. The gain of the 2SC3180-O will be in the range from 55 to 160, for the 2SC3180-R it will be in the range from 55 to 110.Sometimes the "2S" prefix is not marked on the package - the 2SC3180 might only be marked "C3180".The complementary PNP transistor to the 2SC3180 is the 2SA1263.The BDP951 (SOT-223) is the SMD version of the 2SC3180 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC3180 with the 2SC2563, 2SC2577, 2SC2578, 2SC2579, 2SC2580, 2SC2581, 2SC2706, 2SC2837, 2SC3181, 2SC3181-O, 2SC3181N, 2SC3181N-O, 2SC3182, 2SC3182-O, 2SC3280, 2SC3284, 2SC3519, 2SC3853, 2SC3854, 2SC3855, 2SC4466, 2SC4467, 2SC4468, 2SC4688, 2SC4689, 2SC4690, 2SC5196, 2SC5197, 2SC5198, 2SC5199, 2SD1148, 2SD712, 2SD716, 2SD731, 2SD998, BD245B, BD245C, BD249B, BD249C, BDV93, BDV95, FJA4310, KTD718, KTD718B, KTD998 or TIP35CA.
