BC558CRL1

Single Bipolar Transistors Overview

The BC558CRL1 is a PNP epitaxial silicon small-signal transistor manufactured by onsemi. It is housed in a TO-92 (TO-226AA) three-pin plastic package designed for through-hole mounting. The device features a maximum collector current of 100 mA and a collector-emitter voltage rating of 30 V. It operates with a maximum power dissipation of 500 mW and supports junction temperatures up to 150 °C. This component belongs to the complementary BC546–BC550 series, offering high DC current gain suitable for general-purpose amplification and switching applications.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix RL1 against official datasheets to confirm packaging details and compliance status. Ensure the procurement source provides documentation confirming the component matches the BC558C specifications. Cross-reference the manufacturer's part number to avoid confusion with similar variants that may have different electrical tolerances or pinout orientations.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with 30 V collector-emitter voltage and 100 mA continuous current capability is required. It serves as the complementary pair to the BC557C and BC559C within the same family. Consider its low noise profile for sensitive analog front-end designs where signal integrity is critical compared to standard switching transistors.

Single Bipolar Transistors Part Context

The BC558CRL1 is part of the broader BC55x series from onsemi, which includes complementary NPN devices like the BC548. These transistors are widely used in consumer electronics and industrial control systems due to their standardized TO-92 footprint and reliable performance. The series is known for providing matched hFE bins for balanced differential pairs in precision analog applications.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include the BC558CTA and BC558CZL1G from various manufacturers. Verify that replacement parts maintain the same 30 V VCEO rating and TO-92 mechanical dimensions to ensure direct board compatibility without circuit modification.
