MMBTA55-TP

Single Bipolar Transistors Overview

The MMBTA55-TP is a PNP general-purpose amplifier transistor manufactured by Micro Commercial Components (MCC). It utilizes silicon technology and is housed in an SOT-23-3 surface-mount package. The device supports a continuous collector current of -500 mA and offers a collector-emitter breakdown voltage (V(BR)CEO) of -60 V, with a collector-base breakdown voltage (V(BR)CBO) of -80 V. Power dissipation is rated at 225 mW, and the transition frequency (fT) reaches 50 MHz. Operating junction temperature ranges from -55 °C to +150 °C.

Single Bipolar Transistors Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase to avoid counterfeit components. Confirm the -TP suffix indicates tape-and-reel packaging containing 3,000 pieces per reel. Ensure procurement channels provide full traceability and adherence to MCC quality standards for storage and handling.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring a PNP transistor with a -60 V collector-emitter voltage rating and -500 mA current capacity. The SOT-23-3 package suits space-constrained surface-mount layouts. Consider the 225 mW power dissipation limit and thermal resistance when designing heat management strategies for the application environment.

Single Bipolar Transistors Part Context

This part belongs to the MMBTA55/56 series of PNP bipolar junction transistors. While sharing the same physical SOT-23-3 package and general structure, the MMBTA55 differs from the MMBTA56 primarily in its voltage ratings, specifically offering a -60 V V(BR)CEO compared to the MMBTA56's -80 V rating.

Single Bipolar Transistors Replacement Considerations

Cross-reference with other PNP SOT-23 transitors such as the BC857 or MMBTA56 if higher voltage ratings are acceptable. Verify pinout compatibility and ensure replacement parts meet the required -500 mA current and -60 V voltage specifications.
