BC807-40QAZ

Overview

The BC807-40QAZ is a PNP general-purpose transistor manufactured by Nexperia USA Inc. It operates with a collector-emitter voltage of -45 V and a maximum collector current of -500 mA. The device features a DC current gain (hFE) ranging from 250 to 600 at -100 mA, with a minimum gain of 40 at -500 mA. It utilizes a DFN1010D-3 (SOT1215) leadless package with visible solderable side pads, measuring 1.1 x 1.0 x 0.37 mm. Key electrical limits include a collector-base voltage of -50 V and an emitter-base voltage of -5 V. Total power dissipation reaches 900 mW under specific PCB mounting conditions, with a junction temperature limit of 150 °C.

Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation to ensure correct package type and gain binning. Confirm that the DFN1010D-3 footprint matches your PCB design requirements. Check for any recent Product Change Notices regarding assembly sites or material updates. Ensure compatibility with your reflow soldering profile for this specific ultra-thin package variant.

Selection Notes

Select this component when space-constrained designs require a low-profile surface-mount transistor. The DFN1010D-3 package offers reduced height compared to traditional SOT-23 variants. Verify thermal management capabilities based on your specific PCB copper area and layer count, as power dissipation ratings vary significantly with mounting conditions. Ensure the required hFE range aligns with your circuit's biasing needs.

Part Context

This part belongs to the BC807 series of PNP general-purpose transistors produced by Nexperia. The 'QA' suffix indicates the DFN1010D-3 package variant, distinguishing it from standard SOT-23 versions. The '40' designation specifies the DC current gain range of 250 to 600. This series serves as the PNP complement to the BC817 NPN transistor family.

Replacement Considerations

BC807-25QAZ shares the same DFN1010D-3 package but offers a lower current gain range (160-400). Standard SOT-23 packages like BC807-40 are pin-compatible in function but differ physically. Verify thermal resistance values if replacing with non-DFN variants due to different heat dissipation characteristics.
