Single Bipolar Transistors datasheet and documents for BC549CTA

BC549CTA

Single Bipolar Transistors Overview

The BC549CTA is an NPN epitaxial silicon transistor from the BC546–BC550 series, manufactured by onsemi. It features a collector-emitter voltage of 30 V and a continuous collector current of 100 mA. The device belongs to the 'C' gain classification, providing a DC current gain range of 420 to 800 at 2 mA. Designed for low-noise applications, it exhibits a noise figure between 1.4 dB and 4.0 dB. The component is housed in a TO-92 package with kinked leads and supplied in an ammo pack.

Single Bipolar Transistors Feature Summary

Low-noise design optimized for sensitive signal amplification
High DC current gain suitable for precision switching and linear operation
Epitaxial silicon construction for stable performance

Single Bipolar Transistors Applications

Low-noise audio pre-amplifiers
General-purpose signal amplification circuits
Electronic switching applications

Single Bipolar Transistors Procurement Notes

Verify the manufacturer origin, as this part was originally a Fairchild Semiconductor product now integrated into ON Semiconductor. Confirm the specific ordering suffix matches the required packaging format. Ensure compliance with RoHS standards and check for any updated nomenclature changes resulting from corporate integration processes before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when high current gain and low noise characteristics are required for small-signal processing. The 'C' classification provides the highest gain tier within the BC549 family. Consider the TO-92 through-hole package constraints and verify that the 30 V collector-emitter rating aligns with the target circuit's maximum operating voltages.

Single Bipolar Transistors Part Context

This transistor is part of the broader BC546 through BC550 family of NPN epitaxial silicon transistors. The BC549 variant specifically targets low-noise requirements compared to other members like the BC547 or BC548. It serves as the complementary counterpart to the PNP BC559 transistor within the same product line.
