Compact surface mount PNP transistor Nexperia BC856B215 for switching and amplification applications
Product Overview
The Nexperia BC856, BC857, and BC858 series are PNP general-purpose transistors designed for a wide range of switching and amplification applications. These transistors are housed in a compact SOT23 (TO-236AB) surface-mounted device (SMD) plastic package, offering low current (max. 100 mA) and low voltage (max. 65 V) capabilities. They are suitable for general-purpose use where reliable performance in a small form factor is required.
