Classification of hFE
The KTD2060 transistor can have a current gain of 40 to 240. The gain of the KTD2060O will be in the range from 70 to 140, for the KTD2060R it will be in the range from 40 to 80, for the KTD2060Y it will be in the range from 120 to 240.
Complementary PNP transistor
The complementary PNP transistor to the KTD2060 is the KTB1368.
SMD Version of KTD2060 transistor
The BDP951 (SOT-223) is the SMD version of the KTD2060 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
