BC847CT-TP

Overview

The BC847CT-TP is a single NPN bipolar junction transistor manufactured by Micro Commercial Components. It utilizes silicon technology and is housed in an SOT-523-3 surface-mount package. Key electrical ratings include a maximum collector current of 100 mA, a collector-emitter voltage of 45 V, and a collector-base voltage of 50 V. The device features a minimum DC current gain (hFE) of 420 at 2 mA and 5 V, with a transition frequency of 100 MHz. Power dissipation is rated at 150 mW, and the operating temperature range spans from -55°C to +150°C.

Feature Summary

• High DC current gain for efficient signal amplification
• Compact SOT-523-3 surface-mount footprint
• Wide operating temperature range suitable for diverse environments

Applications

• General-purpose signal amplification
• Switching applications in low-power circuits
• Audio pre-amplifier stages

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with the manufacturer or authorized distributors before integration. Confirm that the SOT-523-3 package dimensions match your PCB layout requirements. Ensure that thermal management strategies account for the 150 mW power dissipation limit under expected operating conditions to maintain reliability within the specified temperature range.

Selection Notes

Select this component when a compact NPN transistor with high current gain is required for space-constrained designs. The BC847CT-TP offers a balance of moderate voltage handling and significant amplification capability. Consider the SOT-523-3 package size relative to available board space and compare performance metrics against alternative transistors if higher voltage ratings or different packaging options are necessary for the specific application constraints.

Part Context

This part belongs to the BC847 series of small-signal NPN transistors produced by Micro Commercial Components. The 'C' suffix typically denotes a specific binning of current gain characteristics, ensuring consistent performance across production batches. The '-TP' suffix indicates the specific ordering and packaging configuration provided by MCC. This series is widely used in consumer electronics and industrial control systems requiring reliable switching and amplification functions.

Replacement Considerations

Direct pin-compatible replacements may include other manufacturers' BC847C variants in SOT-523 packages, such as those from Diodes Inc. or Nexperia. Verify that substitute parts meet or exceed the 45V VCEO rating, 100mA Ic limit, and hFE minimums. Always review the replacement's datasheet for differences in saturation voltage and thermal resistance to ensure circuit compatibility.
