The KTA1272O 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.
Here is an image showing the pin diagram of this transistor.The KTA1272O transistor can have a current gain of 100 to 200. The gain of the KTA1272 will be in the range from 100 to 320, for the KTA1272Y it will be in the range from 160 to 320.The complementary NPN transistor to the KTA1272O is the KTC3204O.The 2SA1036 (SOT-23), 2SA1036-P (SOT-23), 2SA1182 (SOT-23), 2SA1204 (SOT-89), 2SA1204-O (SOT-89), 2SA1588 (SOT-323), 2SA1621 (SOT-23), 2SA1621-O (SOT-23), FJX1182 (SOT-323), KSA1182 (SOT-23), KTA1298 (SOT-23), KTA1298-O (SOT-23), KTA1505 (SOT-23), KTA1505S (SOT-23), KTA1664 (SOT-89), KTA1664O (SOT-89), KTC8550S (SOT-23) and KTC8550S-C (SOT-23) is the SMD version of the KTA1272O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTA1272O with the 2N4951, 2N4952, 2N4954, 2SA1020, 2SA1150, 2SA1150-O, 2SA1271, 2SA1271-O, 2SA1273, 2SA1273-O, 2SA1283, 2SA1534A, 2SA684, 2SA928A, 2SA928A-O, 2SA950, 2SA950-O, 2SA966, 2SA966-O, 2SB1229, 2SB1229-R, 2SB740, 2SB740-B, 2SB764, 2SB764-E, 2SB892, 2SB892-R, 2SB985, 2SB985R, KSA928A, KSA928A-O, KTA1271, KTA1271O, KTA1273, KTA1273O, KTA1281, KTA1282, KTA1282O, KTA708, KTA708-Y, KTB764, KTB764-Y, STB1277 or STB1277-O.
