BC556BTAR

Single Bipolar Transistors Overview

The BC556BTAR is a PNP epitaxial silicon transistor manufactured by onsemi, designed for general-purpose switching and amplification applications. It operates within a collector-emitter voltage of -65 V and a collector-base voltage of -80 V, with a maximum continuous collector current of -100 mA. The device features a power dissipation rating of 500 mW at 25°C ambient temperature and a transition frequency (fT) of 150 MHz. It is housed in a TO-92 three-pin through-hole package with kinked leads, suitable for high-volume production via reel packaging.

Single Bipolar Transistors Feature Summary

• PNP epitaxial silicon construction optimized for low-current general-purpose operations
• High-voltage capability supporting up to -65 V collector-emitter breakdown
• Through-hole TO-92 package design facilitating standard board mounting

Single Bipolar Transistors Applications

• General purpose signal amplification circuits
• Low-speed electronic switching applications
• Complementary pairing with NPN transistors such as the BC546 series

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'AR' against the manufacturer's official datasheet to confirm the exact tape-and-reel quantity and lead finish specifications. Ensure the procurement documentation explicitly references the onsemi BC556BTAR part number to distinguish it from similar variants like BC556BTA or BC556BTF. Confirm RoHS compliance status directly from the component marking or latest product change notice.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with -65 V collector-emitter voltage and -100 mA continuous current capacity is required. The TO-92 form factor makes it suitable for prototyping and low-power consumer electronics where through-hole assembly is preferred. Consider the 150 MHz transition frequency for basic audio or low-frequency signal processing tasks rather than high-speed RF applications.

Single Bipolar Transistors Part Context

This component belongs to the BC556 family of PNP silicon transistors produced by onsemi. It serves as the PNP counterpart to the BC546 NPN transistor, often used in matched pairs for differential amplifier stages. The BC556 series is widely recognized for its reliability in general-purpose analog and digital switching circuits across various industrial and consumer electronic devices.
