BC212B TRE PBFREE

Single Bipolar Transistors Overview

The BC212B TRE PBFREE is a single NPN silicon small-signal transistor manufactured by Central Semiconductor Corp. It utilizes a TO-92 (TO-226AA) cylindrical plastic package with three leads. The device features a maximum collector-emitter voltage of 50V and a maximum collector current of 100mA. DC current gain (hFE) is specified within the 'B' bin range, typically starting at a minimum of 200. Power dissipation is rated at 500mW at an ambient temperature of 25°C.

Single Bipolar Transistors Feature Summary

• NPN polarity configuration for general-purpose amplification and switching applications
• High DC current gain characteristics suitable for low-level signal processing
• Through-hole mounting capability via standard TO-92 leaded package

Single Bipolar Transistors Applications

• General purpose amplifier circuits
• Low noise signal switching
• Small signal processing stages

Single Bipolar Transistors Procurement Notes

Verify the specific hFE binning requirements against the manufacturer's datasheet to ensure compatibility with circuit gain thresholds. Confirm that the TO-92 package dimensions align with the target PCB footprint. Ensure the procurement channel provides official Central Semiconductor documentation to validate RoHS compliance and material composition for the final assembly process.

Single Bipolar Transistors Selection Notes

Select this component when a moderate voltage rating of 50V and a continuous current capacity of 100mA are required in a compact through-hole form factor. The BC212B variant offers higher current gain than standard BC212 units, making it preferable for high-gain amplifier stages where base drive current must be minimized. Consider thermal constraints if operating near the maximum power dissipation limit.

Single Bipolar Transistors Part Context

This part belongs to the widely recognized BC212 family of NPN transistors, originally defined by Philips/NXP specifications. Central Semiconductor produces the BC212B TRE PBFREE as a lead-free, halogen-free alternative compliant with modern environmental directives. The 'TRE' suffix indicates reel packaging, while 'PBFREE' confirms the absence of lead in the terminations.

Single Bipolar Transistors Replacement Considerations

Direct pin-compatible substitutes include the BC212L and BC212K from various manufacturers, though hFE ranges differ. Cross-reference with ON Semiconductor or Diodes Inc equivalents such as the MMBT3904 only if voltage ratings permit, noting the lower current limits of SMD alternatives.
