BC558BTFR

Single Bipolar Transistors Overview

The BC558BTFR is a PNP silicon epitaxial planar transistor manufactured by onsemi, housed in a TO-92 (TO-226AA) lead-free package. It features a maximum collector current of 100 mA and a collector-emitter voltage rating of 30 V. The device offers a minimum DC current gain (hFE) of 200 at 2 mA and 5 V, with a transition frequency of 150 MHz. Power dissipation is rated at 500 mW, and it operates within a temperature range of -55°C to +150°C junction temperature.

Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer marking and date code upon receipt, as onsemi acquired Fairchild Semiconductor assets. Ensure the component matches the BC558BTFR specification sheet regarding hFE binning and thermal characteristics. Confirm RoHS compliance status through official documentation provided by the supplier, as legacy stock may vary.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with 30V VCEO and 100mA IC is required in a TO-92 package. The BC558B variant provides a standardized hFE range starting at 200. Consider the BC557 or BC559 if higher voltage ratings or different gain bands are necessary for the specific circuit design requirements.

Single Bipolar Transistors Part Context

The BC558 series belongs to a family of complementary NPN/PNP transistors widely used in analog electronics. The BC558BTFR specifically denotes the tape-and-reel packaging format from onsemi, facilitating automated assembly. This part is functionally equivalent to other manufacturers' BC558B devices, ensuring broad industry compatibility for replacement and design-in purposes.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include BC558B from Diotec or Rochester Electronics. For higher voltage needs, consider BC557B (45V). For lower voltage, BC556B (65V) is available. Verify pinout compatibility (E-B-C) across all replacements.
