BC328-25

Single Bipolar Transistors Overview

The Diotec Semiconductor BC328-25 is a general-purpose PNP bipolar junction transistor (BJT) designed for commercial and industrial applications. It features a maximum collector current of 800 mA, a collector-emitter breakdown voltage of 25 V, and a power dissipation rating of 625 mW. The device operates within a junction temperature range of -55°C to +150°C. DC current gain (hFE) is specified in three groups; the -25 suffix indicates a minimum gain of 160 at 100 mA and 1 V. The transistor utilizes a TO-92 through-hole package.

Single Bipolar Transistors Feature Summary

• General-purpose PNP transistor suitable for signal processing, switching, and amplification tasks
• Three distinct DC current gain groups available for varied circuit requirements
• Compliant with RoHS, REACH, and Conflict Minerals regulations

Single Bipolar Transistors Applications

• Signal processing circuits
• Electronic switching applications
• Amplification stages

Single Bipolar Transistors Procurement Notes

Verify that the specific part number matches the required electrical characteristics, particularly the 25 V collector-emitter voltage limit. Confirm compliance with AEC-Q101 standards if automotive-grade reliability is necessary, as standard versions are designated for commercial or industrial use only. Ensure the TO-92 package dimensions align with the target PCB layout constraints.

Single Bipolar Transistors Selection Notes

Select this component when a low-voltage PNP transistor is required for general-purpose switching or amplification. The BC328-25 variant provides a guaranteed minimum hFE of 160 at 100 mA. Designers must account for the lower voltage rating compared to the BC327 series. Verify thermal management capabilities, as the 625 mW dissipation rating depends on lead temperature conditions.

Single Bipolar Transistors Part Context

The BC328-25 belongs to the BC327/BC328 family of universal PNP transistors manufactured by Diotec Semiconductor. This series offers complementary options to NPN transistors like the BC337 and BC338. The product line supports various gain groupings (-16, -25, -40) to accommodate different amplification needs across commercial and industrial electronic designs.

Single Bipolar Transistors Replacement Considerations

The BC327-25 serves as a direct functional substitute, offering identical current and gain specifications but with an increased collector-emitter voltage rating of 45 V.
