BC559CTA is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists onsemi. Its product description is TRANS PNP 30V 0.1A TO-92-3. Review the specifications below when checking this part for your BOM.
The onsemi BC559CTA is a PNP general-purpose bipolar junction transistor (BJT) designed for low-power amplification and switching applications. It features a maximum DC collector current of -100 mA and a collector-emitter voltage rating of -30 V. The device operates within a temperature range of -55°C to +150°C, with a maximum power dissipation of 500 mW. Packaged in a TO-92 case, it offers a minimum DC current gain (hFE) of 100 and a transition frequency of 10 MHz.
Verify the specific suffix 'CTA' against the manufacturer's official datasheet to confirm binning or packaging specifications. Ensure the component matches the required hFE range and thermal characteristics for the intended application. Cross-reference the part number with authorized distributors to confirm availability and authenticity.
Select this component for applications requiring a PNP transistor with moderate current handling and voltage ratings. Consider the TO-92 package constraints for thermal management. Evaluate the hFE requirements against the circuit design needs. Compare with other members of the BC556-BC559 series if different gain levels are necessary.
The BC559CTA belongs to the BC556-BC559 family of PNP transistors from onsemi. These devices are widely used as general-purpose switches and amplifiers. The BC559 specifically offers higher current gain compared to lower-numbered variants in the series, making it suitable for applications requiring better amplification performance.
Compatible substitutes include BC559BU and BC559BZL1. Verify pinout compatibility and electrical parameters such as VCEO and IC before substitution.
