NEXPERIA BC817 NPN General Purpose Transistor 500mA SOT-323 SMD

The NEXPERIA BC817 is a 500mA NPN general purpose transistor designed for a wide range of electronic applications. Engineered for both general purpose switching and amplification, this bipolar junction transistor (BJT) provides reliable performance in low voltage environments whilst accommodating high current requirements.

A notable feature of the BC817 series is its complementarity with the BC807 PNP transistor, allowing for flexible circuit design in push-pull configurations. It comes in a compact SOT-323 surface mount device (SMD) package, which is ideal for space-constrained printed circuit board layouts. With a maximum collector emitter voltage of 45V and a continuous collector current of 500mA, it is well-suited for driving moderate loads.
