BC546CTA

Single Bipolar Transistors Overview

The BC546CTA is an NPN epitaxial silicon transistor from the onsemi BC546 series, housed in a TO-92-3 Ammo package. It features a collector-emitter voltage of 65 V and a maximum DC collector current of 100 mA. The device provides a DC current gain (hFE) range of 420 to 800 at 2 mA and 5 V. Key electrical parameters include a collector-base voltage of 80 V, emitter-base voltage of 6 V, and power dissipation of 500 mW. The transition frequency is 300 MHz, with a noise figure between 2.0 and 10.0 dB.

Single Bipolar Transistors Procurement Notes

Verify the specific 'C' hFE binning classification against circuit requirements. Confirm the TO-92-3 Ammo packaging format matches assembly line specifications. Ensure compliance with RoHS directives as indicated in the datasheet documentation.

Single Bipolar Transistors Selection Notes

Select this component when high DC current gain and low noise are required alongside standard voltage ratings. The 'C' grade offers superior gain consistency compared to lower grades. Verify thermal management capabilities for the TO-92 package under continuous operation conditions.

Single Bipolar Transistors Part Context

This part belongs to the BC546/BC547/BC548/BC549/BC550 series of NPN epitaxial silicon transistors. Originally manufactured by Fairchild Semiconductor, these parts are now integrated into the onsemi portfolio following corporate acquisition. The series maintains standardized pinouts and mechanical dimensions across variants.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC546BTA and BC546ATA from the same manufacturer. Cross-manufacturer equivalents such as Fairchild BC546CTA or generic BC546C variants may be used if electrical characteristics align.
