2SC2073 Transistor Pinout and Pin Configurations
Pinout Configuration of 2SC2073
| Pin No. | Pin Name | Description |
|---|---|---|
| 1 | Base (B) | Controls the transistor’s switching, small current at base controls large current between the collector and emitter pins. |
| 2 | Collector (C) | This is the main current carrying terminal. connected to load in most circuits. |
| 3 | Emitter (E) | Current flows out through this terminal to ground or negative side of supply. |
