BC308BBU

Single Bipolar Transistors Overview

The BC308BBU is a PNP bipolar junction transistor manufactured by onsemi, housed in a TO-92-3 through-hole package. It features a maximum collector-emitter voltage of 25 V and a continuous collector current rating of 100 mA. The device has a power dissipation capacity of 500 mW and a transition frequency of 130 MHz. DC current gain (hFE) is specified at a minimum of 180 when tested at 2 mA base current and 5 V collector-emitter voltage. The saturation voltage is limited to 500 mV under conditions of 5 mA base current and 100 mA collector current. The component supports a maximum junction temperature of 150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm pinout and electrical tolerances. Confirm RoHS compliance status as required by project specifications. Note that this product is listed as obsolete; check for availability of last-time buy options or approved alternative components from the manufacturer before finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring a low-voltage PNP transistor with moderate current handling capabilities. Ensure the circuit operates within the 25 V collector-emitter breakdown limit and does not exceed the 100 mA continuous current rating. Verify that the thermal management strategy accommodates the 500 mW power dissipation limit at the expected ambient operating temperatures.

Single Bipolar Transistors Part Context

This part belongs to the BC307-09 series of small-signal transistors produced by onsemi. The series includes complementary NPN and PNP variants designed for similar low-power applications. The BC308BBU specifically provides the PNP counterpart option within this family, sharing similar physical dimensions and basic switching characteristics with its series peers.

Single Bipolar Transistors Replacement Considerations

Consult the official BC307-09 datasheet for confirmed substitute part numbers. Verify pin compatibility and electrical parameter equivalence before integrating any replacement components into existing designs.
