Pinout of BC237A
The BC237A 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 collector, base, and emitter leads. Here is an image showing the pin diagram of this transistor.
Classification of hFE
The BC237A transistor can have a current gain of 120 to 220. The gain of the BC237 will be in the range from 120 to 800, for the BC237B it will be in the range from 180 to 460, for the BC237C it will be in the range from 380 to 800.
Complementary PNP transistor
The complementary PNP transistor to the BC237A is the BC307A.
SMD Version of BC237A transistor
The 2SC1623 (SOT-23), BC847 (SOT-23), BC847A (SOT-23), BC847AW (SOT-323), BC847W (SOT-323), BC850 (SOT-23), BC850A (SOT-23), BC850AW (SOT-323), BC850W (SOT-323) and KSC1623 (SOT-23) is the SMD version of the BC237A transistor.
