The BC817-16 SOT-23 Bipolar Transistor with ROHS manufactured by Changjing Electronics Technology is a NPN-type (Negative-Positive-Negative) silicon epitaxial transistor commonly used in amplification, switching, and other types of circuits. It has a maximum power dissipation of 500mW, maximum collector current of 250mA, and a maximum DC current gain of 470. Its gain bandwidth is 390MHz, and its transition frequency is 1GHz. The transistor is rated with peak collector-emitter voltage of 45V and peak emitter-base voltage of 5V. It is configured in a SOT-23 (Small Outline Transistor-23) package with three terminals. This part is designed for use in applications such as radio frequency (RF) amplifiers, modem circuitry, and RF switches. It is suitable for commercial applications that require low power dissipation.
