Single Bipolar Transistors Procurement Notes

Verify the ordering suffix matches the required packing method, as the BC327,126 designation corresponds to tape and reel packaging in wide pitch SOT54A format. Confirm the specific hFE selection group if precise gain ranges are critical for the design. Ensure compatibility with the SOT54 footprint dimensions during PCB layout verification.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a 500 mA continuous current rating and 45 V breakdown voltage is required. Consider the SOT54 package constraints for thermal management, noting the 200 K/W junction-to-ambient resistance. Verify that the required DC current gain falls within the standard 100 to 600 range or select a specific sub-type like BC327-16, -25, or -40 for tighter gain tolerances.

Single Bipolar Transistors Part Context

The BC327 belongs to a family of PNP general-purpose transistors alongside the BC807 and BC807W variants. While the BC807 uses surface-mount packages like SOT23 and SOT323, the BC327 is specifically designated for the through-hole SOT54 package. This family shares similar electrical characteristics but differs in physical form factor and mounting style.
