BC556TF

Single Bipolar Transistors Overview

The onsemi BC556TF is a PNP epitaxial silicon bipolar junction transistor (BJT) designed for general-purpose switching and amplification applications. It operates in a single configuration within a TO-92-3 package with kinked leads, suitable for through-hole mounting. The device supports a maximum continuous collector current of 100 mA and withstands a collector-emitter voltage (VCEO) of 65 V, with a collector-base voltage (VCBO) rating of 80 V. It features a low collector-emitter saturation voltage of 250 mV and a power dissipation capacity of 500 mW. The transition frequency (fT) is specified at 150 MHz, ensuring adequate performance for high-speed switching. The component functions reliably across an operating temperature range up to +150°C.

Single Bipolar Transistors Feature Summary

• Epitaxial silicon construction provides stable electrical characteristics for reliable operation.
• Low collector-emitter saturation voltage enables efficient switching with minimal power loss.
• High transition frequency supports effective performance in high-speed signal processing.
• Robust thermal capability allows sustained operation at elevated temperatures.

Single Bipolar Transistors Applications

• General-purpose amplifier circuits
• Electronic switching applications
• Driver stages for relay or LED control

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'TF' against the manufacturer's official datasheet to confirm the exact packaging type, typically reel or cut tape, as this affects handling procedures. Ensure the procurement documentation explicitly lists the BC556TF part number to distinguish it from similar variants like BC556BTA or BC556BTFR. Confirm RoHS compliance status directly from the supplier's certificate of conformity prior to ordering.

Single Bipolar Transistors Selection Notes

Select the BC556TF when a PNP transistor with a 65 V collector-emitter breakdown voltage and 100 mA current capacity is required. This component is appropriate for designs needing a low saturation voltage and a transition frequency of 150 MHz. Consider the TO-92-3 kinked lead package for through-hole assembly constraints. Compare against the BC556B series if higher gain binning is not critical, as the TF suffix denotes specific manufacturing lot attributes rather than distinct electrical parameters.

Single Bipolar Transistors Part Context

The BC556TF belongs to the BC556 family of PNP transistors manufactured by onsemi. This series is widely utilized in consumer electronics and industrial equipment for signal amplification and switching tasks. The TF designation indicates a specific packaging variant, often associated with automated assembly processes using reels or cut tapes, differing from bulk or ammo pack options found in other suffixes like BU or TA.

Single Bipolar Transistors Replacement Considerations

The BC556BTA and BC556BTFR are confirmed parameter-equivalent replacements for the BC556TF. These alternatives share identical electrical ratings, including 65 V VCEO, 100 mA IC, and 500 mW Pd. Verify that the replacement package matches the PCB footprint requirements, as all listed options utilize the TO-92-3 form factor.
