Here is an image showing the pin diagram of this transistor.The KSC2690A-O transistor can have a current gain of 100 to 200. The gain of the KSC2690A will be in the range from 60 to 320, for the KSC2690A-R it will be in the range from 60 to 120, for the KSC2690A-Y it will be in the range from 160 to 320.The complementary PNP transistor to the KSC2690A-O is the KSA1220A-O.The 2N5551S (SOT-23), DXT5551 (SOT-89), DZT5551 (SOT-223), KST5551 (SOT-23) and MMBT5551 (SOT-23) is the SMD version of the KSC2690A-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSC2690A-O with the 2SC2690A, 2SC2690A-Q, 2SC3117, 2SC3117-R, 2SC3902, 2SC3902-R, 2SD669A, 2SD669A-C or KTC2800.
