BC856 is a PNP bipolar junction transistor (BJT) that is designed for low-power switching and amplification applications. It is a complementary transistor to the BC846 NPN transistor, and together they can be used in complementary transistor pairs to form a variety of circuits.
Some technical specifications of the BC856 transistor are:
Maximum Collector Current: 100 mA
Maximum Collector-Emitter Voltage: -65 V
Maximum Collector-Base Voltage: -80 V
DC Current Gain (hFE): 110 to 800
Operating Temperature Range: -55°C to +150°C
Package: SOT-23 Surface Mount Package
RoHS Compliant: Yes
The BC856 transistor is a PNP transistor, which means that it conducts current when the base-emitter junction is reverse-biased. It is commonly used in circuits that require low-power switching and amplification, such as audio amplifiers, small signal amplifiers, and oscillators. The SOT-23 package of the BC856 transistor is small and easy to handle, making it ideal for space-constrained applications.
The transistor has a high DC current gain (hFE), which allows for a small base current to control a larger collector current. This makes it suitable for applications that require amplification of weak signals or switching of small loads. When used in complementary pairs with NPN transistors such as the BC846, they can be used in push-pull configurations to amplify and switch AC signals.
