| BC556 THRU BC559 Small Signal Transistors (PNP) TO-92 .181 (4.6) min. .492 (12.5) .181 (4.6) .142 (3.6) FEATURES PNP Silicon Epitaxial Planar Transistors for switching and AF amplifier applications. These transistors are subdivided into three groups A, B and C according to their current gain. The type BC556 is available in groups A and B, however, the types BC557 and BC558 can be supplied in all three groups. The BC559 is a low-noise type available in all three groups. As complementary types, the NPN transistors BC546 ... BC549 are recommended. On special request, these transistors are also manufactured in the pin configuration TO-18. max. .022 (0.55) .098 (2.5) C B E MECHANICAL DATA Case: TO-92 Plastic Package Weight: approx. 0.18 g Dimensions in inches and (millimeters) MAXIMUM RATINGS AND ELECTRICAL CHARACTERISTICS Ratings at 25 C ambient temperature unless otherwise specified Symbol Collector-Base Voltage BC556 BC557 BC558, BC559 BC556 BC557 BC558, BC559 BC556 BC557 BC558, BC559 -VCBO -VCBO -VCBO -VCES -VCES -VCES -VCEO -VCEO -VCEO -VEBO -IC -ICM -IBM IEM Ptot Tj TS Value 80 50 30 80 50 30 65 45 30 5 100 200 200 200 5001) 150 -65 to +150 Unit V V V V V V V V V V mA mA mA mA mW C C Collector-Emitter Voltage Collector-Emitter Voltage Emitter-Base Voltage Collector Current Peak Collector Current Peak Base Current Peak Emitter Current Power Dissipation at Tamb = 25 C Junction Temperature Storage Temperature Range 1) Valid provided that leads are kept at ambient temperature at a distance of 2 mm from case. 4/98 BC556 THRU BC559 ELECTRICAL CHARACTERISTICS Ratings at 25 C ambient temperature unless otherwise specified Symbol h-Parameters at -VCE = 5 V, -IC = 2 mA, f = 1 kHz Current Gain Current Gain Group A B C Input Impedance Current Gain Group A B C Output Admittance Current Gain Group A B C Reverse Voltage Transfer Ratio Current Gain Group A B C DC Current Gain at -VCE = 5 V, -IC = 10 A Current Gain Group A B C at -VCE = 5 V, -IC = 2 mA Current Gain Group A B C at -VCE = 5 V, -IC = 100 mA Current Gain Group A B C Thermal Resistance Junction to Ambient Air Collector Saturation Voltage at -IC = 10 mA, -IB = 0.5 mA at -IC = 100 mA, -IB = 5 mA Base Saturation Voltage at -IC = 10 mA, -IB = 0.5 mA at -IC = 100 mA, -IB = 5 mA Base-Emitter Voltage at -VCE = 5 V, -IC = 2 mA at -VCE = 5 V, -IC = 10 mA Collector-Emitter Cutoff Current BC556 at -VCE = 80 V at -VCE = 50 V BC557 BC558 at -VCE = 30 V BC556 at -VCE = 80 V, Tj = 125 C at -VCE = 50 V, Tj = 125 C BC557 BC558, BC559 at -VCE = 30 V, Tj = 125 C 1) Min.
