BC556ATA

Single Bipolar Transistors Overview

The onsemi BC556ATA is a PNP general-purpose bipolar junction transistor (BJT) housed in a TO-92 three-pin through-hole package. It features a maximum collector-emitter voltage (VCEO) of -65 V and a collector-base voltage (VCBO) of -80 V. The device supports a maximum DC collector current (IC) of -100 mA with a power dissipation (Pd) of 500 mW. It operates within a temperature range of -55°C to +150°C, offering a minimum DC current gain (hFE) of 120 and a transition frequency (fT) of 10 MHz.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'ATA' against official onsemi documentation to confirm binning or grading specifications. Ensure the component matches the required hFE range and packaging format for your design. Confirm availability status as distribution data may vary by region.

Single Bipolar Transistors Selection Notes

Select this component for low-current PNP switching tasks requiring robust thermal performance. Compare hFE bins if precise gain control is necessary. Ensure the TO-92 footprint fits the PCB layout constraints. Verify voltage ratings against circuit peaks to maintain safety margins.

Single Bipolar Transistors Part Context

This part belongs to the BC556 series of PNP silicon epitaxial planar transistors. The series is subdivided into groups based on current gain characteristics. These devices are designed for general-purpose use in both switching and audio amplifier applications, providing a reliable solution for low-power electronic designs.

Single Bipolar Transistors Replacement Considerations

Check for direct substitutes such as BC556BTA or BC556BTFR from onsemi. Verify pinout compatibility and electrical parameter equivalence before substitution.
