Here is an image showing the pin diagram of this transistor.The 2SC3422-Y transistor can have a current gain of 120 to 240. The gain of the 2SC3422 will be in the range from 80 to 240, for the 2SC3422-O it will be in the range from 80 to 160.Sometimes the "2S" prefix is not marked on the package - the 2SC3422-Y might only be marked "C3422-Y".The complementary PNP transistor to the 2SC3422-Y is the 2SA1359-Y.The 2SC2873 (SOT-89), 2SC2873-Y (SOT-89), BDP947 (SOT-223) and FMMT619 (SOT-23) is the SMD version of the 2SC3422-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC3422-Y with the 2SC2877, 2SD1348, 2SD1683, 2SD1722, 2SD1723, 2SD794, 2SD794A, BD131, BD175, BD175-16, BD177, BD179, BD187, BD189, BD785, BD787, BD787G, BD789, BDX35, BDX36, BDX37, KSD794, KSD794A, KSE180, KSE181, KSE182, MJE180, MJE180G, MJE181, MJE181G, MJE182, MJE182G, MJE222, MJE225 or MJE242.
