The BC856W-QF is a PNP general-purpose bipolar junction transistor manufactured by Nexperia. It is housed in the SOT-323 (SC-70) surface-mount plastic package. The device features a maximum collector current of 100 mA and a collector-emitter voltage rating of 65 V. Key electrical parameters include a collector-base voltage of 80 V, an emitter-base voltage of 5 V, and a DC current gain (hFE) minimum of 125 at 2 mA and 5 V. The transition frequency is 100 MHz, with power dissipation rated at 200 mW. Operating temperatures range from -65 °C to +150 °C.
Verify the specific suffix 'QF' against official Nexperia documentation to confirm it denotes the AEC-Q101 qualified variant rather than a standard commercial grade. Confirm that the ordering part number matches the exact qualification level required for your design. Ensure compatibility with the SOT-323 footprint during procurement planning.
Select this component when automotive-grade reliability is mandated for small-signal PNP switching tasks. The SOT-323 package offers space efficiency for dense PCB layouts. Verify that the 65 V collector-emitter voltage and 100 mA current limits align with the circuit requirements before finalizing the selection.
This part belongs to the Nexperia BC856W series of general-purpose transistors. The 'Q' designation typically indicates AEC-Q101 qualification for automotive applications. It serves as the PNP complement to the BC846W NPN transistor within the same package family, providing matched characteristics for complementary circuit designs.
The BC846W is the NPN complement within the same series. For direct replacement, verify if the application requires the PNP polarity or if an NPN equivalent like the BC846B is suitable. Check datasheets for pinout and electrical parameter alignment.
