Operating and Storage Junction Temperature Range: -55 to +150 °C
Package: TO-92
Pinout of 2N2923
The 2N2923 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, base, and collector leads. Here is an image showing the pin diagram of this transistor.
SMD Version of 2N2923 transistor
The MMBTH10 (SOT-23) is the SMD version of the 2N2923 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
