BCR22PN-AQ

Overview

The BCR22PN-AQ is an automotive-grade digital transistor manufactured by Diotec Semiconductor, designed for robust switching applications in demanding environments. This component integrates a single NPN bipolar junction transistor with an internal base resistor network to simplify circuit design and reduce board space. It features a collector-emitter voltage (VCEO) of 50 V and a continuous collector current capability of 100 mA, housed in a compact SOT-323 surface-mount package. The device is qualified under the AEC-Q101 standard, ensuring reliability for automotive electronics. Key electrical parameters include a DC current gain (hFE) typically ranging from 100 to 200 at specified test conditions, and a power dissipation rating of 200 mW. It operates within a temperature range of -55°C to +150°C, supporting high-temperature automotive operations.

Procurement Notes

Verify the specific ordering suffix and tape/reel specifications directly with authorized distributors or the manufacturer before placing orders. Confirm that the delivered components carry the correct automotive grade marking and traceability documentation required for production integration. Ensure compliance with RoHS and REACH directives as stated in the official datasheet.

Selection Notes

Select this component when an automotive-qualified NPN digital transistor with integrated biasing is required. The SOT-323 package offers a small footprint ideal for dense PCB layouts. Consider the 50 V VCEO and 100 mA Ic ratings to ensure adequate headroom for the intended switching loads. Verify the internal resistor value matches the drive requirements of the controlling logic source.

Part Context

The BCR22PN-AQ belongs to Diotec's portfolio of automotive-grade discrete semiconductors. It is part of the broader category of digital transistors, which combine transistors and resistors into a single package. The 'AQ' suffix typically denotes AEC-Q101 qualification, distinguishing it from standard commercial variants. This series supports the increasing demand for reliable, miniaturized components in modern automotive electronic control units.

Replacement Considerations

Check for direct pin-compatible substitutes from other manufacturers that meet AEC-Q101 standards. Verify that alternative parts match the 50 V VCEO, 100 mA Ic, and SOT-323 package dimensions. Ensure the internal resistor ratio and hFE characteristics are comparable to maintain circuit performance without redesign.
