Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'TRE' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure the part number matches the exact Central Semiconductor Corp designation for lead-free TO-92 variants. Cross-reference datasheet revisions to confirm current RoHS compliance status and pinout configurations before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when a high-voltage NPN transistor with low noise characteristics is required in a through-hole package. The BC546A variant offers a specific hFE binning that may differ from other letters in the series. Consider thermal management requirements given the 500 mW power dissipation limit in the TO-92 case. Verify compatibility with complementary PNP devices like the BC556 if push-pull configurations are needed.

Single Bipolar Transistors Part Context

This component belongs to the BC546 series of NPN epitaxial silicon transistors. The series includes variants such as BC546B and BC546C, which differ primarily in their DC current gain ranges. The BC546A typically represents a lower gain bin compared to B or C variants. The series is widely used in consumer electronics and industrial control systems requiring reliable small-signal amplification.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include BC546A from other manufacturers such as ON Semiconductor, Fairchild, or NXP. Ensure the replacement maintains the same TO-92 package and lead-free specification. Verify that the alternative part meets the 65V VCEO and 100mA IC ratings.
