BC80840MTF

Overview

The BC80840MTF is a PNP bipolar junction transistor manufactured by onsemi, housed in an SOT-23 surface-mount package. It features a maximum DC collector current of 800mA and a maximum collector-emitter voltage of 30V. The device has a single configuration with three pins and supports a maximum power dissipation of 310mW. Key electrical limits include a collector-base voltage of -10V, an emitter-base voltage of -5V, and a maximum operating frequency of 50MHz. It operates within a temperature range up to +150°C.

Feature Summary

• PNP polarity for signal amplification and switching applications
• Compact SOT-23 surface-mount footprint for space-constrained designs
• High current handling capability up to 800mA
• Robust thermal performance supporting operation up to 150°C

Applications

• General-purpose amplifier circuits
• Low-side switching loads
• Signal processing stages requiring PNP topology

Procurement Notes

Verify the specific suffix 'TF' against the official onsemi datasheet to confirm tape-and-reel packaging specifications and moisture sensitivity level. Ensure the component matches the exact voltage rating of 30V required by the circuit design. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability. Confirm RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a PNP transistor with 800mA continuous current capacity is needed in a small outline package. The 30V collector-emitter voltage rating suits low-voltage logic interfaces. Consider the 310mW power dissipation limit for thermal management requirements. Compare gain bandwidth and saturation voltages against alternative PNP devices if high-frequency response or low-loss conduction is critical for the specific application scenario.

Part Context

This part belongs to the BC808 series of PNP transistors from onsemi, designed for general-purpose use. The BC808 series is widely recognized for its reliability in consumer electronics and industrial control systems. The BC80840 variant specifically denotes the 30V rating version within this family, distinguishing it from lower voltage counterparts like the BC808-16 or higher voltage options.

Replacement Considerations

BC808-40 (Infineon) offers similar PNP characteristics but may differ in packaging details or specific parameter tolerances. Verify pinout compatibility and absolute maximum ratings before substitution.
