BC849B-TP

Overview

The BC849B-TP is an NPN bipolar junction transistor manufactured by Micro Commercial Components. It operates with a maximum collector-emitter voltage of 30V and a continuous collector current of 100mA. The device features a gain bandwidth product of 100MHz and a power dissipation rating of 225mW. It is housed in a surface-mount SOT-23-3 package and supports an operating temperature range from -55°C to +150°C.

Feature Summary

• NPN single transistor configuration for signal amplification
• Surface-mount SOT-23-3 packaging for automated placement
• High thermal stability across extended temperature ranges

Applications

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

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Micro Commercial Components before integration. Confirm that the SOT-23-3 pinout matches your PCB footprint design requirements. Ensure storage conditions adhere to moisture sensitivity level guidelines to prevent package damage during soldering processes.

Selection Notes

Select this component when a compact NPN transistor with moderate current handling and standard voltage ratings is required. The SOT-23-3 form factor suits space-constrained designs. Verify that the 100mA current limit and 30V breakdown voltage align with your circuit's operational peaks and steady-state loads.

Part Context

This part belongs to the BC849 series of small-signal NPN transistors produced by Micro Commercial Components. The series is designed for general-purpose switching and amplification tasks. The BC849B variant specifically denotes a particular DC current gain binning classification within the broader family lineup.

Replacement Considerations

BC849C-TP offers higher gain characteristics within the same package. BC848AW-TP provides similar functionality but utilizes a smaller SOT-323 footprint.
