BC546BTFR

Single Bipolar Transistors Overview

The BC546BTFR is an NPN silicon epitaxial planar transistor manufactured by onsemi. It is housed in a lead-free TO-92 (SOT-54) plastic package designed for through-hole mounting. The device features a maximum collector current of 100 mA and a collector-emitter breakdown voltage of 65 V. It offers a minimum DC current gain (hFE) of 200 at a collector current of 2 mA and Vce of 5 V. The component supports a maximum power dissipation of 625 mW and operates within a junction temperature range of -55°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify the manufacturer marking matches onsemi specifications. Confirm the package type is TO-92 and the suffix indicates tape and reel delivery if required. Ensure RoHS compliance status aligns with project requirements. Check for any specific handling instructions regarding ESD sensitivity during assembly processes.

Single Bipolar Transistors Selection Notes

Select this component when a general-purpose NPN transistor with high current gain is required. It serves as a complement to the PNP BC557B. Consider the 65V breakdown voltage and 100mA current limit for circuit design constraints. Verify thermal management needs for the specified power dissipation level in the final application environment.

Single Bipolar Transistors Part Context

This part belongs to the BC546 series of NPN general-purpose transistors. It is functionally similar to parts from other manufacturers such as Fairchild or NXP under the same base model number. The 'TFR' suffix typically denotes tape and reel packaging for automated assembly, distinguishing it from bulk pack variants.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include BC546B from other manufacturers like NXP or Fairchild. Ensure pinout compatibility and electrical parameters match the original design requirements before substitution.
