BC847BW/DG,115

Overview

The BC847BW/DG,115 is a single NPN general-purpose bipolar junction transistor manufactured by Nexperia USA Inc. It operates with a maximum collector-emitter voltage of 45 V and a continuous collector current of 100 mA. The device utilizes the SOT-323 (SC-70) surface-mount package, measuring 2.2 mm in length and 1.1 mm in height. Key electrical parameters include a minimum DC current gain (hFE) of 200 at 2 mA and 5 V, a transition frequency (fT) of 100 MHz, and a power dissipation rating of 200 mW. The component supports an operating temperature range from -65°C to +150°C.

Feature Summary

• Compact leadless SMD plastic package design suitable for space-constrained applications
• High DC current gain selection ensuring consistent amplification performance
• Wide operating temperature range supporting diverse environmental conditions

Applications

• General-purpose switching circuits
• Signal amplification stages
• Mobile electronic devices

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm exact binning and packaging specifications. Ensure compatibility with standard SMT assembly processes for the SOT-323 footprint. Confirm RoHS compliance status through the manufacturer's latest declaration before integration into regulated products.

Selection Notes

Select this component when a low-profile NPN transistor is required for high-frequency signal processing or switching tasks. The 45 V breakdown voltage provides adequate headroom for low-voltage logic interfaces. Consider the 200 mW thermal limit during circuit design to ensure reliable operation under continuous load conditions.

Part Context

This part belongs to the BC847 series of general-purpose NPN transistors offered by Nexperia. The series includes variants with different gain ranges and complementary PNP types. The BC847BW specifically denotes the B-gain bin within the SOT-323 package family, widely used in consumer electronics and industrial control systems requiring small form factors.

Replacement Considerations

Direct pin-compatible substitutes include other BC847B variants in the SOT-323 package from Nexperia or equivalent parts from manufacturers like ON Semiconductor and Diodes Inc., provided they meet the 45 V, 100 mA, and hFE=200 requirements.
