Here is an image showing the pin diagram of this transistor.The 2SA1285A-F transistor can have a current gain of 250 to 500. The gain of the 2SA1285A will be in the range from 150 to 800, for the 2SA1285A-E it will be in the range from 150 to 300.Sometimes the "2S" prefix is not marked on the package - the 2SA1285A-F might only be marked "A1285A-F".The complementary NPN transistor to the 2SA1285A-F is the 2SC3245A-F.You can replace the 2SA1285A-F with the 2SA1376 or KTA1279.
