BC847CW/SNX

Overview

The BC847CW/SNX is a single NPN general-purpose transistor manufactured by Nexperia USA Inc. It utilizes the SNX (DFN1006B-3) surface-mount package with dimensions of 1.0 mm x 1.0 mm x 0.45 mm. The device features a maximum collector-emitter voltage (VCEO) of 45 V and a maximum DC collector current (IC) of 100 mA. Key electrical parameters include a minimum DC current gain (hFE) of 250 at IC = 2 mA, a transition frequency (fT) of 100 MHz, and a maximum power dissipation (Pd) of 150 mW. The component operates within a temperature range of -55°C to +150°C junction temperature.

Feature Summary

• Ultra-thin DFN1006B-3 package design for high-density PCB layouts
• High DC current gain selection for efficient amplification
• Low collector capacitance for improved switching performance

Applications

• General-purpose switching circuits
• Small-signal amplification stages
• Portable battery-powered devices

Procurement Notes

Verify the specific suffix 'SNX' against official Nexperia documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure the selected hFE bin matches the circuit requirements, as gain ranges vary within the BC847C series. Cross-reference the DFN1006B-3 footprint with the manufacturer's recommended land pattern to guarantee proper soldering reliability during assembly.

Selection Notes

Select this component when board space is constrained due to its compact 1.0x1.0 mm footprint. The BC847C variant provides higher current gain than A or B variants, suitable for low-current amplification tasks. Verify that the 150 mW power dissipation rating aligns with the thermal management capabilities of the target application environment.

Part Context

This part belongs to the BC847 family of small-signal NPN transistors designed for general-purpose applications. The SNX package represents a modern alternative to traditional SOT-23 packages, offering reduced height and improved thermal characteristics through direct die attachment to the substrate.

Replacement Considerations

Direct pin-compatible replacements include other manufacturers' parts in the DFN1006B-3 package with matching 45V/100mA ratings. Verify equivalent hFE bins and thermal resistance values before substitution.
