BC556ATA is a PNP epitaxial silicon bipolar junction transistor from onsemi. It is intended for switching and amplifier applications, with a maximum collector-emitter voltage of 65 V and a maximum collector current of 100 mA. The device provides a minimum DC current gain (hFE) of 110 at Ic=2 mA and Vce=5 V, and a transition frequency of 150 MHz.
The transistor has a maximum power dissipation of 500 mW at 25 °C ambient, derated at 4 mW/°C above 25 °C. The maximum VCE(sat) is 650 mV at Ib=5 mA and Ic=100 mA, and 300 mV at Ib=0.5 mA and Ic=10 mA. Collector cut-off current is 15 nA maximum, and output capacitance is typically 6 pF. The junction temperature can reach 150 °C.
The device comes in a through-hole TO-226-3 / TO-92-3 (TO-226AA) package with formed leads, also known as TO-92-3. It is Pb-free, halogen-free, and RoHS compliant, making it suitable for general-purpose low-power circuits in signal processing, switching, and amplification.
