BC546B A1G

Single Bipolar Transistors Overview

The BC546B A1G is an NPN silicon small-signal bipolar junction transistor manufactured by Taiwan Semiconductor Corporation. It is housed in a TO-92 (TO-226AA) three-pin through-hole package with dimensions of 5.1mm length and 4.7mm height. The device supports a maximum collector current of 100mA and a collector-emitter breakdown voltage of 65V, with a collector-base voltage rating of 80V. Electrical characteristics include a minimum DC current gain (hFE) of 220 at 2mA and 5V, and a maximum power dissipation of 500mW. Operating temperatures range from -65°C to 150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'A1G' against official Taiwan Semiconductor documentation to confirm binning or marking variations. Ensure the component meets RoHS3 compliance standards as indicated for this product line. Confirm availability status directly with the manufacturer or authorized distributors, as supply conditions may vary.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with moderate voltage ratings and high current gain is required for through-hole designs. Compare hFE minimums against circuit requirements to ensure adequate amplification. Verify thermal management needs relative to the 500mW dissipation limit in the TO-92 package.

Single Bipolar Transistors Part Context

This part belongs to the BC546 series of NPN transistors, which are widely used in general electronics. The 'B' designation typically indicates a specific current gain bin compared to other variants like BC546A or BC546C. The series is known for reliability in consumer and industrial electronic equipment.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC546B from other manufacturers such as ON Semiconductor or Micro Commercial Components, provided pinouts and electrical parameters match. Verify package compatibility and thermal characteristics before substitution.
