Here is an image showing the pin diagram of this transistor.The KTC2814 transistor can have a current gain of 70 to 240. The gain of the KTC2814-O will be in the range from 70 to 140, for the KTC2814-Y it will be in the range from 120 to 240.The complementary PNP transistor to the KTC2814 is the KTA1715.The 2SC2873 (SOT-89), 2SC3444 (SOT-89), BCP55 (SOT-223) and BCX55 (SOT-89) is the SMD version of the KTC2814 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTC2814 with the 2SD1722, 2SD1723, 2SD1724, 2SD1725, 2SD794A, BD177, BD179, BD189, BD235, BD235G, BD237, BD237G, BD377, BD379, BD787, BD787G, BD789, BD791, BDX35, BDX36, BDX37, KSD794A, KSE181, KSE182, MJE181, MJE181G, MJE182, MJE182G, MJE225, MJE242 or MJE244.
