BC847BPNHF

Overview

The BC847BPNHF 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 electrostatic discharge protection characteristics integrated into the silicon structure

Applications

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

Procurement Notes

Verify the exact ordering code against manufacturer datasheets to ensure correct binning and packaging specifications. Confirm that the SOT-323 footprint matches the design intent. Check for RoHS compliance status if required by specific regional regulations. Ensure storage conditions adhere to moisture sensitivity level requirements prior to reflow soldering.

Selection Notes

Select this component when a compact NPN transistor with moderate voltage ratings and high current gain is required. Compare hFE bins against circuit requirements for consistent amplification factors. Evaluate thermal management needs based on the 225 mW power dissipation limit in the SOT-323 package. Consider alternative packages like SOT-23 if higher power handling or different pinout compatibility is necessary.

Part Context

This part belongs to the BC847 series of small-signal NPN transistors, widely used in general-purpose electronic designs. The 'BP' suffix indicates the specific SOT-323 surface-mount package variant. The 'NHF' designation typically refers to tape-and-reel packaging for automated assembly processes. This series is a standard replacement for older through-hole equivalents in modern miniaturized devices.
