Classification of hFE
The KSD880 transistor can have a current gain of 60 to 300. The gain of the KSD880-G will be in the range from 150 to 300, for the KSD880-O it will be in the range from 60 to 120, for the KSD880-Y it will be in the range from 100 to 200.
Complementary PNP transistor
The complementary PNP transistor to the KSD880 is the KSB834.
