BC307ABU

Single Bipolar Transistors Overview

The BC307ABU is a PNP silicon epitaxial planar transistor manufactured by onsemi. It is housed in a TO-92-3 through-hole package and designed for general-purpose switching and amplification applications. The device features a maximum collector current of 100 mA and a collector-emitter breakdown voltage of 45 V. Key electrical characteristics include a DC current gain (hFE) minimum of 100 at 100 mA and 1 V, a transition frequency of 100 MHz, and a maximum power dissipation of 625 mW. The saturation voltage is specified at 700 mV under standard test conditions.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'ABU' against the official onsemi datasheet to confirm the hFE binning and packaging details. Ensure the component matches the required TO-92-3 form factor and lead configuration for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with moderate current handling and low-voltage operation is required. Compare the 100 mA collector current limit and 45 V breakdown voltage against circuit demands. Consider the TO-92-3 package constraints for thermal management and board space compared to higher-power alternatives.

Single Bipolar Transistors Part Context

This component belongs to the BC307 series of small-signal PNP transistors. It shares the same physical package and basic structure as other variants in the family but differs in gain classification and specific electrical tolerances defined by the ABU suffix. It serves as a complementary or standalone device in low-power analog and digital designs.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include the BC327 series for similar PNP specifications. Verify pinout compatibility and ensure the replacement meets the 100 mA current and 45 V voltage requirements. Check datasheets for matching hFE ranges and saturation voltages to maintain circuit performance.
