BC847BPNHX

Overview

The BC847BPNHX is a small-signal NPN transistor manufactured by Nexperia, housed in an SOT-323 surface-mount package. It features a collector-emitter voltage (Vceo) of 45 V and a collector current (Ic) of 100 mA. The device offers a DC current gain (hFE) range of B-grade, typically between 160 and 250 at Ic = 2 mA. Key electrical parameters include a collector-base breakdown voltage (Vcbo) of 60 V and an emitter-base breakdown voltage (Vebo) of 5 V. The maximum power dissipation is 225 mW at 25°C ambient temperature, with a junction temperature range from -55°C to +150°C.

Feature Summary

• Compact SOT-323 surface-mount package designed for space-constrained PCB layouts
• High DC current gain suitable for low-power amplification applications
• Robust thermal performance with defined power dissipation limits

Applications

• General-purpose switching circuits
• Low-noise audio pre-amplifiers
• Signal processing stages in consumer electronics

Procurement Notes

Verify the exact suffix 'H' indicates tape-and-reel packaging configuration when sourcing. Confirm the manufacturer's datasheet revision matches the required specifications for voltage and gain ranges. Ensure compatibility with automated pick-and-place equipment due to the small SOT-323 footprint. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a compact NPN transistor with moderate current handling and high gain is required. Compare against alternative SOT-323 devices if specific pinout or thermal resistance values differ. Ensure the operating voltage remains within the 45 V limit and current stays below 100 mA for reliable operation.

Part Context

This part belongs to Nexperia's BC847 series of small-signal transistors. The BC847 family includes variants with different gain grades (A, B, C). The BC847B specifically denotes the B-grade gain bin. The PN suffix indicates the SOT-323 package type, while HX refers to the reel packaging format.

Replacement Considerations

Direct substitutes include other BC847B variants in SOT-323 packages from manufacturers like ON Semiconductor or STMicroelectronics. Verify that replacement parts match the 45 V Vceo and 100 mA Ic ratings. Ensure the gain range aligns with circuit design requirements.
