BC184

Single Bipolar Transistors Overview

The BC184 is a silicon NPN small signal transistor manufactured by onsemi. It features a collector-emitter voltage (VCEO) of 30 V and a continuous collector current (IC) of 100 mA. The device has a maximum power dissipation of 350 mW at 25°C, with a thermal resistance junction-to-ambient of 357 °C/W. DC current gain (hFE) is specified as a minimum of 130 at IC = 100 mA and VCE = 5 V. The transition frequency (fT) is 150 MHz. Operating and storage junction temperatures range from -55°C to +150°C.

• Audio pre-amplifiers

Single Bipolar Transistors Procurement Notes

Verify the manufacturer origin, as the BC184 was originally a Fairchild Semiconductor product now owned by onsemi. Confirm the package type matches the required footprint, typically TO-92. Check datasheet revisions for any parameter updates. Ensure compliance with RoHS directives if applicable to the target market. Validate component authenticity through authorized distribution channels.

Single Bipolar Transistors Selection Notes

Select this component for low-power NPN switching or linear amplification tasks requiring moderate voltage handling. Consider the 30 V breakdown limit and 100 mA current capacity against circuit demands. Evaluate thermal management needs given the 350 mW dissipation rating in free air. Compare hFE requirements with specific load conditions to ensure adequate drive margins.

Single Bipolar Transistors Part Context

The BC184 belongs to the family of small signal bipolar junction transistors (BJTs). It serves as a fundamental discrete semiconductor component used in electronic design for signal processing and control functions. Historically associated with Fairchild Semiconductor, production rights are held by onsemi following corporate acquisitions.

Single Bipolar Transistors Replacement Considerations

BC182: Offers higher voltage ratings (50 V VCEO) but lower gain (min 80 hFE). BC184L: Provides tighter gain binning for consistent performance. BC547: Common alternative with similar electrical characteristics and pinout compatibility.
