BC847A-AQ

Overview

The BC847A-AQ is an NPN bipolar junction transistor manufactured by Diotec Semiconductor, designed for surface-mount applications in the SOT-23 package. It is qualified to AEC-Q101 standards for automotive reliability. The device supports a maximum collector current of 100 mA and a collector-emitter voltage (Vceo) of 45 V. Key electrical characteristics include a DC current gain (hFE) minimum of 110 at 2 mA and 5 V, a transition frequency (fT) of 100 MHz, and a maximum power dissipation of 250 mW. It operates within a temperature range of -55°C to +150°C.

Feature Summary

Automotive-grade qualification compliant with AEC-Q101 standards
High DC current gain ensuring efficient signal amplification
Compact SOT-23 surface-mount packaging for space-constrained designs

Applications

Automotive electronic control units
General-purpose switching circuits
Signal amplification stages

Procurement Notes

Verify the specific suffix and manufacturer documentation to confirm AEC-Q101 compliance and exact hFE binning. Ensure the sourcing channel provides original manufacturer data sheets. Cross-reference the part number with official distributor catalogs to validate authenticity and avoid counterfeit components.

Selection Notes

Select this component when automotive reliability and compact form factors are required. Compare the 100 mA current rating and 45 V voltage limit against circuit requirements. Consider the SOT-23 footprint constraints and thermal dissipation capabilities relative to the application's power budget.

Part Context

This part belongs to the BC847 series of small-signal NPN transistors. The '-AQ' suffix typically denotes automotive qualification. It serves as a general-purpose replacement for standard BC847 variants where higher reliability and specific gain ranges are mandated by automotive or industrial specifications.
