BC556 PNP Transistor

Description

BC556 Bipolar Transistor Characteristics of the BC556 bipolar transistor Type –PNP Collector-Emitter Voltage:– 65V Collector-Base Voltage:– 80V Emitter-Base Voltage:– 5V Collector Current:-0.1A Collector Dissipation :- 0.5W DC Current Gain (hfe) :- 110 to 800 Transition Frequency :- 150 MHz Noise Figure :- 2 dB Operating and Storage Junction Temperature Range -65 to 150 C Package :- TO-92 Pin configuration (Pinout) of the BC556 The BC556 is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the collector, base, and emitter leads. Here is an image showing the pin diagram of the this transistor. Classification of hFE The BC556 transistor might have a current gain anywhere between 110 and 800. The gain of the BC556A will be in the range from 110 to 220,BC556B ranges from 200 to 450, BC556C ranges from 420 to 800. Complementary NPN transistor The complementary NPN transistor to the BC556 is the BC546. SMD Equivalent The SMD versions of the BC556 are available as the BC856 (SOT-23) and BC856W (SOT-323).
