Procurement Notes

Verify the exact suffix configuration against official Infineon documentation, as variations exist within the BCR185 family. Confirm availability status, as specific variants may be subject to discontinuation notices. Ensure compatibility with standard SMD reflow soldering processes for the SOT-323 package. Cross-reference the full part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a compact PNP digital switch with integrated biasing is required. The 10 kOhm input resistance suits direct interfacing with standard logic outputs. Consider the 250 mW power dissipation limit for thermal management in dense layouts. Verify that the 50 V voltage rating meets the circuit's maximum operating conditions.
