BC32825BU

Single Bipolar Transistors Overview

The onsemi BC32825BU is a PNP bipolar junction transistor (BJT) in the BC328 series, housed in a TO-92-3 through-hole package. It features a maximum collector-emitter voltage of 50 V and a continuous collector current of 1 A. The device has a DC current gain (hFE) range of 160 to 320 at 100 mA and 1 V. Key electrical parameters include a transition frequency of 150 MHz, a collector-base breakdown voltage of 80 V, and an emitter-base breakdown voltage of 5 V. Maximum power dissipation is 625 mW, with a saturation voltage of 700 mV at 50 mA base and 500 mA collector currents.

Single Bipolar Transistors Feature Summary

• High current handling capability up to 1 A for robust switching applications
• Wide DC current gain band (160–320) ensuring consistent amplification performance
• Enhanced voltage ratings including 50 V collector-emitter and 80 V collector-base breakdown

Single Bipolar Transistors Applications

• General-purpose amplifier circuits
• Switching applications requiring moderate current drive
• Driver stages for relays or small motors

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'BU' against the manufacturer's official datasheet to confirm pinout and packaging details. Confirm RoHS compliance status as manufacturing processes may change. Check for obsolescence notices or lifecycle notifications from onsemi before finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with higher current capacity than the BC327 series is required. Ensure the application voltage does not exceed 50 V. Verify that the thermal management strategy supports 625 mW dissipation in the TO-92 package. Compare hFE requirements against the 160–320 range.

Single Bipolar Transistors Part Context

The BC32825BU belongs to the BC328 family of PNP transistors, which are successors to the BC327 series. This family offers improved current handling and voltage ratings compared to earlier generations. The part is manufactured by onsemi, a leading provider of semiconductor solutions for energy efficient electronics.

Single Bipolar Transistors Replacement Considerations

BC32825B: Direct equivalent from onsemi with identical specifications. BC328C25: Alternative binning option if higher gain variation is acceptable. BC32725BU: Lower current/voltage alternative; verify suitability for the specific circuit requirements.
