BC32825

Single Bipolar Transistors Overview

The Fairchild Semiconductor BC328-25 is a PNP silicon epitaxial planar transistor designed for general-purpose amplification and switching applications. It features a DC current gain (hFE) range of 250 to 400, ensuring consistent performance across batches. The device is housed in the SOT-23 surface-mount package, providing compact footprint solutions for modern electronics. Key electrical characteristics include a collector-emitter voltage (VCEO) of -40 V and a continuous collector current (IC) of -100 mA. These specifications make it suitable for low-power signal processing tasks.

Single Bipolar Transistors Feature Summary

• High DC current gain classification ensures reliable amplification with minimal base drive requirements.
• Epitaxial planar construction provides robust thermal stability and consistent electrical parameters.
• Surface-mount SOT-23 packaging facilitates automated assembly and space-constrained designs.

Single Bipolar Transistors Applications

• Low-power switching applications in consumer electronics
• Driver stages for LED arrays or small loads

Single Bipolar Transistors Procurement Notes

Verify the specific suffix '25' to confirm the binning category for current gain (hFE). Ensure the component matches the required SOT-23 pinout configuration. Check datasheet revisions for any updates on absolute maximum ratings. Confirm RoHS compliance status if environmental regulations apply to the final assembly.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with moderate current handling and high gain is required. Compare hFE ranges against circuit biasing needs to ensure adequate saturation or linear operation. Consider the SOT-23 thermal dissipation limits for power-intensive designs. Evaluate alternative packages if higher current capacity or different mounting styles are necessary.

Single Bipolar Transistors Part Context

The BC328 series belongs to Fairchild's lineup of general-purpose PNP transistors. The BC328-25 variant specifically targets applications requiring a guaranteed minimum hFE of 250. This binning allows designers to optimize resistor values without accounting for wide gain variations found in unsorted devices.

Single Bipolar Transistors Replacement Considerations

Public confirmed substitute part numbers: BC328B, BC328C, MMBT3906 (with caution regarding gain differences), SS8550 (verify pinout compatibility).
