BC847B-TP

Overview

The BC847B-TP is a single NPN bipolar junction transistor manufactured by Micro Commercial Components. It utilizes silicon technology and is housed in an SOT-23-3 surface-mount package. The device supports a maximum DC collector current of 100 mA and offers a collector-emitter breakdown voltage (VCEO) of 45 V, with a collector-base voltage (VCBO) of 50 V and emitter-base voltage (VEBO) of 6 V. Key electrical characteristics include a minimum DC current gain (hFE) of 200 at 2 mA and 5 V, a transition frequency (fT) of 100 MHz, and a maximum power dissipation of 225 mW. The component operates within a temperature range of -55°C to +150°C.

Procurement Notes

Verify the specific ordering suffix and packaging type, such as Cut Tape or Reel, against the required quantity and handling needs. Confirm that the component meets the necessary RoHS3 compliance standards for the target assembly process. Ensure the selected variant matches the exact pinout and thermal specifications required for the printed circuit board design to avoid integration issues during manufacturing.

Selection Notes

Select this component when a standard NPN transistor with moderate voltage ratings and high current gain is required for compact designs. The SOT-23-3 package is suitable for space-constrained surface-mount assemblies. Consider the 100 mA current limit and 45 V voltage rating to ensure adequate headroom for the intended circuit loads. Verify compatibility with the operating temperature range of the final application environment.

Part Context

This part belongs to the BC847 series of small-signal transistors from Micro Commercial Components. The BC847 family is widely recognized for its reliability in consumer electronics and industrial equipment. The BC847B-TP specifically denotes the B-gain bin, offering higher current gain compared to A-grade variants. It serves as a common replacement for similar NPN transistors in legacy designs requiring SOT-23 packaging.

Replacement Considerations

Compatible substitutes include other NPN transistors in the SOT-23 package with similar VCEO and Ic ratings, such as the BC847A or BC847C, noting differences in hFE gain bins. Cross-reference with generic equivalents like 2N3904 if leaded packages are acceptable, though pinouts differ. Always verify electrical parameters against the original datasheet before substitution.
