FMBA56

Single Bipolar Transistors Overview

The onsemi FMBA56 is a PNP silicon epitaxial planar transistor housed in an SOT-323 surface-mount package. It features a maximum collector-emitter voltage (VCEO) of -80 V and a continuous collector current (IC) of -500 mA. The device has a maximum power dissipation (PD) of 200 mW at 25°C ambient temperature, with a transition frequency (fT) of 100 MHz. Operating temperatures range from -55°C to +150°C junction temperature.

Single Bipolar Transistors Feature Summary

• High-speed switching capability with a transition frequency of 100 MHz for efficient signal processing.
• Robust voltage handling with -80 V collector-emitter breakdown rating suitable for general-purpose applications.
• Compact SOT-323 footprint designed for high-density surface-mount assembly requirements.

Single Bipolar Transistors Applications

• General-purpose amplification circuits
• Switching applications in low-power digital logic interfaces

Single Bipolar Transistors Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout orientation and electrical tolerances. Ensure the ordering code matches the required tape-and-reel quantity specifications. Confirm RoHS compliance status directly with manufacturer documentation prior to integration into regulated supply chains.

Single Bipolar Transistors Selection Notes

Select this component when a compact PNP transistor with -80 V rating and 100 MHz bandwidth is required. Compare thermal resistance values against PCB copper area constraints. Verify that the -500 mA current limit aligns with load requirements without exceeding the 200 mW power dissipation threshold under worst-case operating conditions.

Single Bipolar Transistors Part Context

This part belongs to onsemi's family of small-signal PNP transistors designed for surface-mount technology. It serves as a modern alternative to through-hole equivalents, offering similar electrical characteristics in a significantly reduced physical footprint. The series supports automated assembly processes common in mass-produced electronic devices.

Single Bipolar Transistors Replacement Considerations

Check pinout compatibility before substituting with other SOT-323 PNP transistors. Verify that replacement parts meet or exceed the -80 V VCEO and 100 MHz fT specifications. Ensure thermal performance remains adequate for the intended application environment.
