BC858B-AQ

Overview

The BC858B-AQ is a PNP bipolar junction transistor manufactured by Diotec Semiconductor, designed for surface-mount applications in the SOT-23 (TO-236) package. It features a maximum collector-emitter voltage of -30 V and a continuous collector current of -100 mA. The device operates within a junction temperature range of -55°C to +150°C and has a maximum power dissipation of 250 mW. Certified to AEC-Q101 standards, it ensures reliability for automotive environments.

Feature Summary

Automotive-grade qualification compliant with AEC-Q101 standards
High DC current gain (hFE) binning for consistent amplification performance
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 hFE binning code required for your circuit design, as the 'B' suffix indicates a defined gain range. Confirm that the AEC-Q101 automotive qualification aligns with your system's reliability requirements. Ensure the SOT-23 thermal characteristics are sufficient for your application's power dissipation needs under worst-case operating conditions.

Selection Notes

Select this component when an automotive-qualified PNP transistor is required for low-power switching or amplification. Compare its -30V rating against your circuit's maximum voltage swings. Consider the SOT-23 package constraints regarding thermal management and board space compared to larger packages like TO-92.

Part Context

This part belongs to Diotec's BC8xx series of small-signal transistors. The '-AQ' suffix specifically denotes automotive-grade quality and AEC-Q101 certification, distinguishing it from standard industrial variants. It serves as the PNP counterpart to NPN devices like the BC847 and BC848 within the same family.
