BC184LC

Single Bipolar Transistors Overview

The BC184LC is a silicon NPN small signal transistor manufactured by onsemi, formerly Fairchild Semiconductor. It features a collector-emitter voltage of 30V and a continuous collector current rating of 200mA. The device offers a minimum DC current gain (hFE) of 250 at IC=2mA and 130 at IC=100mA. Key electrical parameters include a transition frequency (fT) of 150MHz, collector-base breakdown voltage of 45V, and maximum power dissipation of 625mW at 25°C ambient temperature. It operates within a junction temperature range up to 150°C and utilizes a TO-92-3 through-hole package.

Single Bipolar Transistors Feature Summary

• High DC current gain with a minimum specification of 250 at low collector currents
• Suitable for general-purpose amplification and switching applications due to fast transition frequency
• Robust thermal performance with a maximum junction temperature rating of 150°C

Single Bipolar Transistors Applications

• General-purpose amplifier circuits
• Low-frequency switching applications
• Audio signal processing stages

Single Bipolar Transistors Procurement Notes

Verify the manufacturer origin carefully, as the component was originally produced by Fairchild Semiconductor before its acquisition by onsemi. Confirm the specific datasheet revision (Rev. A1 or I1) matches your design requirements. Ensure the TO-92-3 package dimensions align with your PCB footprint constraints. Check for any lifecycle status updates regarding discontinuation or last-time buy notifications from authorized distributors.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain NPN transistor is required for low-current amplification tasks. The BC184LC is appropriate for designs needing an hFE of at least 250 at 2mA. Consider the 30V VCEO limit for supply voltages. Compare against other TO-92 transistors if higher current handling or different voltage ratings are needed. Verify noise figure specifications if used in sensitive analog front-end stages.

Single Bipolar Transistors Part Context

The BC184LC belongs to the family of small-signal bipolar junction transistors (BJTs). It is functionally similar to other NPN transistors like the BC184 series but may have specific gain binning differences. These devices are commonly used in consumer electronics, industrial control systems, and communication equipment for basic signal conditioning and switching functions.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include the BC184L and BC184M, which share identical pinouts and electrical characteristics but may differ in gain ranges. Other compatible replacements include the 2N3904 or BC547, though voltage and gain specifications should be verified against the original design requirements.
