The BC556ABU is a PNP epitaxial silicon bipolar junction transistor from onsemi's general-purpose BC556 family. It is designed for switching and amplifier applications, offering a maximum collector-emitter voltage of -65 V and a continuous collector current of -100 mA. The transistor features a DC current gain (hFE) of 110 minimum at IC = -2 mA and VCE = -5 V, and a typical current gain bandwidth product of 150 MHz.
This device is housed in a standard through-hole TO-92-3 package (also known as TO-226-3) with a lead spacing of 2.54 mm. It supports a maximum power dissipation of 500 mW and a junction temperature up to 150 °C. The BC556ABU is Pb-Free, Halogen Free/BFR Free, and RoHS compliant per the manufacturer's datasheet.
As the high-voltage variant of the BC556 family, this transistor is suitable for driving moderate loads and signal amplification in consumer, industrial, and audio electronics. Its complementary NPN counterparts include the BC546, BC547, BC548, BC549, and BC550, enabling push-pull stage designs.
