BC328-25-AP

Single Bipolar Transistors Overview

The BC328-25-AP is a PNP silicon epitaxial planar transistor manufactured by MCC. It features a collector-emitter voltage rating of 45V and a continuous collector current capability of 800mA. The device utilizes a TO-92 (TO-226AA) through-hole package with a standard body configuration. Key electrical parameters include a DC current gain (hFE) range typically starting at 100, a collector-base cutoff current of 200nA, and a transition frequency of 260MHz. Thermal characteristics specify a maximum junction temperature of 150°C and a total power dissipation of 625mW.

Single Bipolar Transistors Feature Summary

• PNP polarity configuration for complementary circuit applications
• Epitaxial planar construction for reliable switching performance
• Through-hole mounting compatibility via TO-92 leaded package

Single Bipolar Transistors Applications

• General-purpose signal amplification
• Complementary output stages in audio circuits
• Switching applications in low-power logic interfaces

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'AP' against the manufacturer's official datasheet to confirm pinout orientation and exact hFE binning. Confirm that the TO-92 package variant matches the required PCB footprint. Ensure the component meets RoHS compliance requirements if mandated by the final assembly specifications.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with moderate current handling and low-voltage operation is required. Compare the 45V rating and 800mA limit against circuit load demands. Consider the thermal resistance of the TO-92 package for heat dissipation needs in enclosed environments.

Single Bipolar Transistors Part Context

This part belongs to the BC328 series of general-purpose PNP transistors. It serves as the PNP counterpart to NPN devices like the BC337 or BC327 family members. The series is widely used in consumer electronics and industrial control boards requiring small-signal amplification.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include the BC327-25-BP from the same manufacturer. Cross-brand equivalents such as the 2SA1015 or BC328-40 may be considered if voltage ratings align with system requirements.
