BC307BTA

Single Bipolar Transistors Overview

The onsemi BC307BTA is a PNP silicon small-signal bipolar junction transistor housed in a TO-92 (TO-226) through-hole package. It features a maximum collector current of 100 mA and a collector-emitter breakdown voltage of 45 V. The device offers a minimum DC current gain (hFE) of 200 at 2 mA and 5 V, with a transition frequency of 150 MHz. Maximum power dissipation is rated at 500 mW, operating within a temperature range of -55°C to 150°C.

Single Bipolar Transistors Feature Summary

• PNP polarity configuration for low-side switching or complementary circuit applications
• High DC current gain ensures effective signal amplification with minimal base drive
• Robust thermal performance supports operation up to 150°C junction temperature

Single Bipolar Transistors Applications

• General-purpose signal amplification in audio and RF circuits
• Complementary pairing with NPN transistors in push-pull output stages
• Switching applications requiring moderate current handling capabilities

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'BTA' against the manufacturer's official datasheet to confirm pinout orientation and hFE binning. Ensure the component source provides valid traceability documentation. Confirm RoHS compliance status as historical batches may vary. Cross-reference the package dimensions with standard TO-92 specifications to guarantee mechanical fit during assembly.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with 45V breakdown and 100mA continuous current is required. The high hFE rating makes it suitable for amplifier stages where base current efficiency is critical. Consider the TO-92 package constraints for thermal management in enclosed designs. Verify that the 150 MHz transition frequency meets the signal bandwidth requirements of the target application.

Single Bipolar Transistors Part Context

The BC307 series represents a legacy family of PNP small-signal transistors widely used in analog electronics. The BC307BTA variant specifically denotes a particular gain binning within the TO-92 form factor. This component serves as a fundamental building block in discrete logic and linear circuits, often replacing older equivalents from other manufacturers while maintaining compatible electrical characteristics.

Single Bipolar Transistors Replacement Considerations

Publicly confirmed substitutes include the BC557BTA and BC307C. Verify pinout compatibility and ensure the replacement part meets or exceeds the 45V Vceo and 100mA Ic ratings. Check for any differences in hFE distribution or transition frequency that might impact circuit stability.
