The BC807K-25R is a PNP general-purpose transistor from the Nexperia BC807K series, housed in a small SOT23 (TO-236AB) surface-mounted plastic package. It features a collector-emitter voltage of -45 V and a continuous collector current of -500 mA. The device offers a DC current gain range of 160 to 400 at VCE = -1 V and IC = -100 mA. It supports a peak collector current of -1 A for single pulses up to 1 ms. The component is qualified under the AEC-Q101 standard for automotive applications.
Verify the specific suffix 'R' against the manufacturer's official documentation to confirm reel packaging specifications. Ensure the ordering code matches the exact BC807K-25 variant required for the intended design. Confirm that the AEC-Q101 qualification status remains valid for the specific production batch being procured.
Select this component when a PNP transistor with a minimum hFE of 160 is required in a compact SOT23 footprint. It serves as the complement to the BC817K-25 NPN transistor. Consider the thermal resistance characteristics if operating near maximum power dissipation limits on standard FR4 PCBs.
This part belongs to the BC807K series, which includes variants with different current gain ranges: BC807K-16 (100-250), BC807K-25 (160-400), and BC807K-40 (250-600). All share identical electrical ratings but differ in amplification factors. The marking code for this specific gain range is HB.
BC817K-25 is the NPN complement within the same family. Other BC807K series members (BC807K-16, BC807K-40) are pin-compatible but have different gain ranges.
