What Is an SOT-23 Bipolar Transistor?
An SOT-23 bipolar transistor is a compact, surface-mount BJT that uses a small base current to switch or amplify collector current. Available in NPN and PNP types, it suits low-power switching, signal conditioning, driver, and bias circuits. Successful selection depends on polarity, pinout, voltage, current, gain, speed, saturation loss, thermal limits, and PCB layout requirements … Read more
