BC556BTA

Single Bipolar Transistors Overview

The onsemi BC556BTA is a PNP epitaxial silicon transistor housed in a TO-92-3 (TO-226AA) through-hole package with kinked leads. It features a maximum collector-emitter voltage of -65 V and a collector-base voltage of -80 V, supporting a continuous DC collector current of -100 mA. The device has a maximum power dissipation of 500 mW and operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a minimum DC current gain (hFE) of 120 and a transition frequency of 150 MHz.

Single Bipolar Transistors Feature Summary

• PNP polarity configuration for signal amplification and switching applications
• High voltage capability with -65 V collector-emitter breakdown
• Through-hole mounting via TO-92-3 package with kinked leads

Single Bipolar Transistors Applications

• General-purpose signal amplification circuits
• Electronic switching applications
• Complementary pairing with NPN transistors

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'BTA' against official datasheets to confirm it denotes the standard tape-and-reel or bulk packaging variant rather than a functional change. Confirm RoHS compliance status directly from the manufacturer's documentation, as historical data may vary by production batch. Ensure the ordering part number matches the exact voltage and gain binning requirements for the design.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with -65 V collector-emitter voltage is required. It serves as a high-voltage alternative to lower-rated counterparts like the BC557. Consider the 150 MHz transition frequency for moderate-speed switching. Verify that the TO-92-3 package dimensions fit the PCB layout constraints.

Single Bipolar Transistors Part Context

The BC556BTA belongs to the BC556 series of PNP epitaxial silicon transistors manufactured by onsemi. This series is designed for general-purpose amplifier and switching uses. The 'BTA' suffix typically indicates the specific packaging format, such as Ammo Pack or Tape & Reel, distinguishing it from other variants like the BTF reel package.

Single Bipolar Transistors Replacement Considerations

BC556BTF is an electrically equivalent alternative with identical specifications but differs in packaging format.
