BC 847C B5003

Single Bipolar Transistors Overview

The BC847CB5003 is an NPN general-purpose small-signal bipolar junction transistor manufactured by Infineon Technologies. It is housed in a SOT-23 surface-mount package and belongs to the BC847 series. The device features a collector-emitter voltage (VCEO) of 45 V, a collector-base voltage (VCBO) of 50 V, and an emitter-base voltage (VEBO) of 6 V. It supports a continuous collector current of 100 mA with a power dissipation of 200 mW. The DC current gain (hFE) ranges from 200 to 450. The transition frequency (fT) is 150 MHz, and it operates within a temperature range of -55 °C to +150 °C.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix B5003 against official Infineon documentation to confirm tape-and-reel quantities and RoHS compliance status. Ensure the component matches the standard BC847CB electrical characteristics. Confirm availability as distribution channels may vary for specific reel configurations.

Single Bipolar Transistors Selection Notes

Select this component when a compact NPN transistor with high gain (200–450 hFE) is required for space-constrained designs. It serves as a complement to the PNP BC857B. Consider the 100 mA current limit and 200 mW power dissipation for thermal management in dense PCB layouts.

Single Bipolar Transistors Part Context

This part is a variant of the widely used BC847 family of NPN transistors. The 'B' designation typically indicates the specific gain binning range of 200 to 450. The '5003' suffix often denotes packaging or lot-specific identifiers rather than functional changes. It is a standard industrial-grade discrete semiconductor component.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include BC847B and BC847C from various manufacturers, provided the gain binning aligns with circuit requirements. Cross-reference datasheets for pinout compatibility in SOT-23 packages.
