The BC807K-40-QR is a PNP general-purpose bipolar junction transistor manufactured by Nexperia. It operates with a maximum collector-emitter voltage of -45 V and supports a continuous collector current of up to 500 mA. The device features a DC current gain (hFE) range of 250 to 600 at a collector current of -100 mA. Packaged in the SOT-363 (SC-88) surface-mount format, it offers high power dissipation capabilities suitable for compact designs. This component is qualified under the AEC-Q101 standard for automotive applications.
Verify the specific suffix 'QR' indicates the reel packaging configuration when sourcing. Confirm the manufacturer is Nexperia USA Inc. or authorized distributor. Ensure the part meets AEC-Q101 requirements if used in automotive contexts. Check datasheet revisions for updated thermal characteristics.
Select this component for designs requiring a PNP transistor with high current capacity in a small footprint. The wide hFE range allows flexibility in biasing networks. Consider the SOT-363 package constraints for PCB layout. Verify thermal management needs against the specified power dissipation limits.
This part belongs to the BC807 series of PNP transistors, complementing the BC817 NPN series. It is designed for general-purpose applications where space is limited. The K-40 designation specifies the voltage rating and gain bin. It serves as a modern alternative to older through-hole packages in portable and automotive devices.
Compatible substitutes include BC807-40 variants from other manufacturers like onsemi or Diodes Incorporated. Ensure pinout compatibility with the SOT-363 package. Verify that replacement parts meet the same AEC-Q101 qualification if automotive use is required.
