BC328

Single Bipolar Transistors Overview

The onsemi BC328 is a PNP silicon epitaxial planar transistor designed for general-purpose switching and amplification applications. It features a collector-emitter voltage (VCEO) of 45 V, a maximum DC collector current (IC) of -800 mA, and a power dissipation (PD) of 625 mW at 25°C ambient temperature. The device operates within a junction temperature range of -55°C to +150°C and offers a DC current gain (hFE) ranging from 100 to 630. Packaged in the TO-92-3 through-hole configuration, it serves as a complementary counterpart to NPN transistors such as the BC337.

Single Bipolar Transistors Feature Summary

Single Bipolar Transistors Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's part number against official datasheets. Confirm compliance with RoHS directives and halide-free specifications. Ensure the package type matches the required TO-92-3 form factor. Validate that the specific hFE binning aligns with circuit design requirements before integration.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with moderate voltage ratings and high current gain is required. It is particularly suitable for designs needing a direct complement to NPN counterparts like the BC337. Consider the thermal management capabilities given the 625 mW dissipation limit in the TO-92 package for low-power applications.

Single Bipolar Transistors Part Context

The BC328 belongs to the widely utilized BC327/BC328/BC329 series of PNP transistors. This family is established for general-purpose use, offering reliable performance in consumer electronics and industrial control systems. Its compatibility with standard NPN equivalents simplifies dual-transistor circuit design and manufacturing processes.

Single Bipolar Transistors Replacement Considerations

The BC32716BU is listed as an obsolete alternative within the same product category. Verify pinout compatibility and electrical parameter equivalence before substitution.
