BC327B

Single Bipolar Transistors Overview

The BC327B is a PNP general-purpose bipolar junction transistor manufactured by Lumimax Optoelectronic Technology. It features an 800 mA continuous collector current and 625 mW power dissipation in a TO-92 package. The device offers a collector-emitter breakdown voltage of -45 V and a collector-base breakdown voltage of -50 V. DC current gain (hFE) ranges from 100 to 630, with specific B-grade classification typically indicating higher gain performance within the family. Transition frequency reaches 260 MHz, supporting switching and amplification applications.

Single Bipolar Transistors Procurement Notes

Verify the specific hFE bin code suffix against the datasheet classification table to confirm gain range. Confirm RoHS compliance status as specifications are subject to change without notice. Ensure the TO-92 package orientation matches the circuit layout requirements before integration.

Single Bipolar Transistors Selection Notes

Select this component for applications requiring moderate current handling and high gain. Compare the -45 V collector-emitter voltage rating against circuit supply levels. Consider the 625 mW power dissipation limit when designing heat management strategies for continuous operation.

Single Bipolar Transistors Part Context

This part belongs to the BC327/BC328 series of PNP transistors. The BC327 variant provides higher voltage ratings compared to the BC328. The 'B' suffix typically denotes a specific DC current gain bin within the manufacturer's production lineup, distinguishing it from standard or other graded variants.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include BC327-16, BC327-25, and BC327-40 depending on required gain. Complementary NPN equivalents like BC337 may be needed for push-pull configurations. Verify pinout compatibility with TO-92 packages.
