The KTA1283Y 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 KTA1283Y transistor can have a current gain of 120 to 200. The gain of the KTA1283 will be in the range from 85 to 300, for the KTA1283GR it will be in the range from 160 to 300, for the KTA1283O it will be in the range from 85 to 160.The complementary NPN transistor to the KTA1283Y is the KTC3211Y.The MMBT3702 (SOT-23), MPS8550S (SOT-23) and MPS8550S-C (SOT-23) is the SMD version of the KTA1283Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTA1283Y with the 2SA1020, 2SA1020Y, 2SA1273, 2SA1273-O, 2SA1680, 2SA928A, 2SA928A-O, 2SA966, 2SA966-O, 2SB1229, 2SB1229-R, 2SB892, 2SB892-R, 2SB985, 2SB985R, KSA1281-Y, KSA928A, KSA928A-O, KTA1273, KTA1273O, KTA1281, KTA1281Y, KTA1282, KTA1282O, STB1277 or STB1277-O.
