The H733 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. The HS733 transistor (with suffix "C") is the center collector version of the H733.
Here is an image showing the pin diagram of this transistor.The H733 transistor can have a current gain of 90 to 600. The gain of the H733-K will be in the range from 300 to 600, for the H733-P it will be in the range from 200 to 400, for the H733-Q it will be in the range from 135 to 270, for the H733-R it will be in the range from 90 to 180.The complementary NPN transistor to the H733 is the H945.The 2SA812 (SOT-23), FJX733 (SOT-323) and KSA812 (SOT-23) is the SMD version of the H733 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SA733 is the TO-92 version of the H733.You can replace the H733 with the 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, A733 or KSA733C.
