Classification of hFE
The KSD794A-Y transistor can have a current gain of 160 to 320. The gain of the KSD794A will be in the range from 60 to 320, for the KSD794A-O it will be in the range from 100 to 200, for the KSD794A-R it will be in the range from 60 to 120.
Complementary PNP transistor
The complementary PNP transistor to the KSD794A-Y is the KSB744A-Y.
SMD Version of KSD794A-Y transistor
The 2STF1360 (SOT-89), 2STN1360 (SOT-223), FZT692B (SOT-223) and NZT560 (SOT-223) is the SMD version of the KSD794A-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
