BC847B

Overview

The Diotec Semiconductor BC847B is a general-purpose NPN bipolar junction transistor (BJT) designed for surface-mount applications. It utilizes an SOT-23 (TO-236) plastic case and operates with a maximum collector current of 100 mA. The device features a collector-emitter breakdown voltage (VCEO) of 45 V and a collector-base voltage (VCBO) of 50 V. Power dissipation is rated at 300 mW for industrial grades and 200 mW for commercial (-C) variants. The component offers three distinct DC current gain groups, with the 'B' group providing a minimum hFE of 200 at IC = 2 mA and VCE = 5 V.

Feature Summary

Features three selectable DC current gain groups to accommodate varying amplification requirements
Constructed using gold bond wires for standard industrial and automotive grades
Complies with RoHS directives without exemptions and adheres to REACH regulations

Applications

Signal processing circuits
Electronic switching applications
General-purpose amplification stages

Procurement Notes

Verify the specific suffix to confirm the operating grade. The absence of a suffix indicates an industrial-grade component, while the -C suffix denotes a commercial-grade variant with lower power dissipation limits. Confirm AEC-Q101 compliance if automotive qualification is required by checking for -Q or -AQ designators. Ensure the ordering code matches the desired current gain group.

Selection Notes

Select this component for low-voltage signal handling where a 45 V collector-emitter rating is sufficient. The BC847B provides higher voltage tolerance than the BC846 series but lower than the BC848 series. Choose the B gain group when a minimum hFE of 200 is necessary. Verify thermal resistance requirements against the PCB layout, as commercial grades have higher thermal resistance compared to industrial versions.

Part Context

This part belongs to the BC846 through BC850 family of SMD universal NPN transistors manufactured by Diotec Semiconductor. These devices share identical pinouts and mechanical dimensions, differing primarily in their collector-emitter voltage ratings and current gain specifications. The BC847B specifically bridges the gap between the 30 V and 65 V voltage classes within the lineup.
