Diotec BC817-40 Diotec Transistor BJT Discrete NPN SOT 23

Diotec BC817-40 is a discrete NPN bipolar junction transistor (BJT) designed for general-purpose amplification and switching applications, housed in a compact SOT-23 package. This silicon-based transistor offers a high current gain of up to 630, making it suitable for low-power amplification and switching circuits. Its characteristics include a maximum continuous collector current of 500 mA and a collector-emitter voltage that can withstand up to 45 V. Engineers often use the BC817-40 in applications such as audio amplification, signal processing circuits, and as a component in power management systems, due to its reliable performance and space-saving design. Additionally, its small form factor makes it ideal for surface-mount technology (SMT) assembly processes in densely packed printed circuit boards (PCBs).
