BC859B-AQ

Overview

The BC859B-AQ is a PNP general-purpose small signal bipolar junction transistor manufactured by Diotec Semiconductor. It utilizes an SOT-23 (TO-236) surface-mount package and operates with a maximum collector current of 100 mA. The device features a collector-emitter breakdown voltage of 30 V and a power dissipation rating of 250 mW at 25°C ambient temperature. It belongs to the Group B current gain category, offering a DC current gain range from 150 to 475 at an IC of 2 mA. The component is AEC-Q101 qualified for automotive applications and supports a junction temperature up to 150°C.

Feature Summary

AEC-Q101 qualified for automotive reliability standards
Three distinct DC current gain groups available
RoHS compliant and free of conflict minerals

Applications

Signal processing circuits
Electronic switching applications
General amplification tasks

Procurement Notes

Verify that the ordering suffix explicitly includes -AQ to confirm AEC-Q101 qualification status. Confirm the specific gain group (Group B) matches design requirements. Ensure the SOT-23 footprint aligns with the PCB layout. Check for RoHS compliance documentation if required by local regulations.

Selection Notes

Select this component when automotive-grade reliability is required for PNP switching or amplification. The Group B gain specification suits moderate amplification needs. Compare thermal resistance values against the commercial grade (-C) variant if operating in high-power environments. Verify complementary NPN availability within the same series for push-pull configurations.

Part Context

This part belongs to the BC856...BC860 family of SMD general-purpose PNP transistors. It serves as the PNP counterpart to the BC847B NPN transistor. The -AQ suffix distinguishes it from standard industrial grades by meeting automotive quality standards. It shares mechanical dimensions with other devices in the TO-236 package family.
