| VISHAY BC856 to BC859 Vishay Semiconductors Small Signal Transistors (PNP) Features * PNP Silicon Epitaxial Planar Transistors for switching and AF amplifier applications. * Especially suited for automatic insertion in thick and thin-film circuits. * These transistors are subdivided into three groups A, B, and C) according to their current gain. The type BC856 is available in groups A and B, however, the types BC857, BC558 and BC859 can be supplied in all three groups. The BC849 is a low noise type. * As complementary types, the NPN transistors BC846...BC849 are recomended. 2 1 1 B 3 18978 C3 E2 Mechanical Data Case: SOT-23 Plastic case Weight: approx. 8.8 mg Marking: BC856A = 3A BC858A = 3J BC856B = 3B BC858B = 3K BC858C = 3L BC857A = 3E BC857B = 3F BC857C = 3G BC859A = 4A BC859B = 4B BC859C = 4C Packaging Codes/Options: GS18 / 10 k per 13" reel (8 mm tape), 10 k/box GS08 / 3 k per 7" reel (8 mm tape), 15 k/box Pinning: 1 = Base, 2 = Emitter, 3 = Collector Document Number 85135 Rev. 1.2, 08-Sep-04 www.vishay.com 1 BC856 to BC859 Vishay Semiconductors Absolute Maximum Ratings Tamb = 25 C, unless otherwise specified Parameter Collector - base voltage Test condition Part BC856 BC857 BC858 BC859 Collector - emitter voltage (base shorted) BC856 BC857 BC858 BC859 Collector - emitter voltage (base open) BC856 BC857 BC858 BC859 Emitter - base voltage Collector current Peak colector current Peak base current Peak emitter current Power dissipation 1) VISHAY Symbol - VCBO - VCBO - VCBO - VCBO - VCES - VCES - VCES - VCES - VCEO - VCEO - VCEO - VCEO - VEBO - IC - ICM - IBM IEM Value 80 50 30 30 80 50 30 30 65 45 30 30 5 100 200 200 200 310 1) Unit V V V V V V V V V V V V V mA mA mA mA mW Tamb = 25 C Ptot Device on fiberglass substrate, see layout on third page.

Meet all present and future national and international statutory requirements. 2. Regularly and continuously improve the performance of our products, processes, distribution and operatingsystems with respect to their impact on the health and safety of our employees and the public, as well as their impact on the environment. It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as ozone depleting substances (ODSs). The Montreal Protocol (1987) and its London Amendments (1990) intend to severely restrict the use of ODSs and forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban on these substances. Vishay Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use of ODSs listed in the following documents. 1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively 2. Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental Protection Agency (EPA) in the USA 3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C (transitional substances) respectively. Vishay Semiconductor GmbH can certify that our semiconductors are not manufactured with ozone depleting substances and do not contain such substances. We reserve the right to make changes to improve technical design and may do so without further notice. Parameters can vary in different applications. All operating parameters must be validated for each customer application by the customer. Should the buyer use Vishay Semiconductors products for any unintended or unauthorized application, the buyer shall indemnify Vishay Semiconductors against all claims, costs, damages, and expenses, arising out of, directly or indirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.
