BC847AS-AU_R1_000A1

Overview

The BC847AS-AU_R1_000A1 is a dual NPN general-purpose transistor manufactured by Panjit International Inc. It features an AEC-Q101 qualification for automotive reliability and operates within a temperature range of -55°C to +150°C. The device utilizes a SOT-363 surface-mount package, integrating two independent NPN transistors in a single compact form factor. Key electrical characteristics include a collector-emitter voltage (Vceo) of 45V and a continuous collector current (Ic) of 100mA per element. The component is designed for low-power switching and amplification applications, offering high DC current gain with a typical hFE range of 200 to 450 at Ic=2mA.

Feature Summary

• Dual NPN configuration providing two independent transistors in a single SOT-363 package for space-constrained designs.
• Automotive-grade AEC-Q101 qualification ensuring robust performance and reliability in demanding environments.
• High DC current gain optimized for efficient signal amplification and logic-level switching operations.

Applications

• General-purpose signal amplification in consumer electronics and industrial control circuits.
• Low-frequency switching applications requiring compact dual-transistor solutions.
• Automotive electronic modules requiring AEC-Q101 qualified components for enhanced durability.

Procurement Notes

Verify the specific suffix AU_R1_000A1 against official Panjit documentation to confirm packaging and tape-and-reel specifications. Ensure compatibility with standard SOT-363 footprint dimensions during PCB layout. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before final procurement approval.

Selection Notes

Select this component when a dual NPN topology is required in a minimal footprint. Compare the 45V Vceo rating against circuit voltage requirements to ensure adequate headroom. Evaluate the 100mA Ic limit against load currents to prevent thermal overstress. Consider the SOT-363 thermal dissipation capabilities relative to ambient operating conditions.

Part Context

This part belongs to the BC847 series of small-signal NPN transistors produced by Panjit. The 'S' designation typically indicates a specific binning or gain classification within the series.
