BC857AM3-TP

Overview

The BC857AM3-TP is a PNP general-purpose signal transistor manufactured by Micro Commercial Components (MCC). It utilizes an epitaxial die construction and is housed in a leadless SOT-723 surface-mount package. The device supports a maximum collector current of 100 mA and a collector-emitter breakdown voltage of -65 V. Key electrical parameters include a transition frequency of 100 MHz, a DC current gain ranging from 200 to 450 at specific test conditions, and a power dissipation rating of 265 mW at 25°C ambient temperature.

Feature Summary

• Halogen-free green device compliant with RoHS standards
• Moisture sensitivity level 1 rating for reliable handling
• Epoxy material meets UL 94 V-0 flammability requirements

Applications

• General-purpose small signal amplification
• Low and medium frequency AC applications
• DC switching circuits

Procurement Notes

Verify the authenticity of the component by checking for the MCC logo and part marking on the package. Ensure the ordering suffix matches the requested specifications. Purchase only from authorized distributors to guarantee traceability and compliance with quality standards. Confirm that the device meets the required environmental and safety certifications before integration into final assemblies.

Selection Notes

Select this component for designs requiring a compact PNP transistor with moderate current handling capabilities. The SOT-723 package offers significant board space savings compared to traditional packages. Consider the thermal resistance and derating curves when designing for high ambient temperatures or continuous operation near maximum ratings.

Part Context

This part belongs to the BC856/BC857/BC858 AM3 series from Micro Commercial Components. These transistors are designed as complementary pairs to NPN devices like the BC847 series. The series provides standardized performance for general-purpose electronics, ensuring interchangeability across various circuit topologies while maintaining consistent electrical characteristics within specified limits.

Replacement Considerations

Direct replacements include other manufacturers' BC857 variants in the SOT-723 package. Verify pinout compatibility and ensure that the substitute device meets or exceeds the original voltage, current, and power dissipation ratings. Check for equivalent gain ranges and saturation voltages to maintain circuit performance.
