The 2SA1767 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 2SA1767 transistor can have a current gain of 60 to 220. The gain of the 2SA1767Q will be in the range from 60 to 150, for the 2SA1767R it will be in the range from 100 to 220.Sometimes the "2S" prefix is not marked on the package - the 2SA1767 might only be marked "A1767".The complementary NPN transistor to the 2SA1767 is the 2SC1473A.The BF621 (SOT-89) and BF821 (SOT-23) is the SMD version of the 2SA1767 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1767 with the 2SA1371, 2SA1624 or KTA1279.
