BC546B TRE PBFREE

Single Bipolar Transistors Overview

The BC546BTRE PBFREE is an NPN silicon epitaxial planar transistor manufactured by Central Semiconductor Corp. It features a maximum collector-emitter voltage of 65 V and a continuous collector current rating of 100 mA. The device is housed in a surface-mount SOT-523 package with a maximum power dissipation of 250 mW. Key electrical characteristics include a DC current gain (hFE) of at least 200 at 2 mA and 5 V, a transition frequency of 100 MHz, and a collector cutoff current of 15 nA. The saturation voltage is specified at 400 mV under standard test conditions.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'TRE' against the manufacturer's official datasheet to confirm it denotes the correct tape-and-reel packaging format for the SOT-523 variant. Ensure the component matches the RoHS3 compliance status and lead-free specifications required for your assembly process. Cross-reference the part number with Central Semiconductor Corp documentation to avoid confusion with similar BC546 series packages.

Single Bipolar Transistors Selection Notes

Select this component when a compact surface-mount NPN transistor is required for low-power applications. The SOT-523 form factor offers space efficiency compared to through-hole alternatives like TO-92. Ensure the design accounts for the 250 mW power dissipation limit and the 65 V breakdown voltage to maintain safe operating area margins during operation.

Single Bipolar Transistors Part Context

This part belongs to the BC546 series of NPN general-purpose transistors. While the base BC546 model is commonly associated with the TO-92 through-hole package, this specific variant utilizes the SOT-523 surface-mount footprint. It shares core electrical parameters with other series members but differs in physical mounting and thermal characteristics due to the smaller package size.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include other manufacturers' BC546B variants in the SOT-523 package, such as those from ON Semiconductor or Diotec. Verify that replacement parts maintain the same hFE binning and pinout configuration to ensure circuit compatibility without redesign.
