Overview
The BC847CW/ZLF is an NPN general-purpose transistor manufactured by Nexperia. It operates with a maximum collector-emitter voltage of 45 V and a continuous collector current of 100 mA. The device is housed in a SOT323 (SC-70) surface-mount plastic package, measuring 2 x 1.25 x 0.95 mm. It features a minimum DC current gain (hFE) of 200 at 2 mA and 5 V. The component supports a maximum power dissipation of 200 mW and functions within a temperature range of -65°C to +150°C.
Feature Summary
- Compact SOT323 surface-mount package for space-constrained designs
- High DC current gain suitable for amplification applications
- General-purpose switching and amplification capabilities
Applications
- General-purpose switching circuits
- Amplifier stages
- Low noise audio equipment
Procurement Notes
Verify the specific suffix ZLF against official Nexperia documentation to confirm lead-free status and RoHS compliance details. Ensure the ordering code matches the exact electrical characteristics required for the design. Cross-reference the package outline dimensions with PCB footprint libraries to guarantee mechanical compatibility during assembly.
Selection Notes
Select this component when a small form factor NPN transistor with high gain is required. The SOT323 package offers significant board space savings compared to larger through-hole alternatives. Consider the 45 V voltage rating and 100 mA current limit to ensure operation remains within safe operating areas for the intended application load.
Part Context
This part belongs to the BC847 series of NPN general-purpose transistors from Nexperia. The series includes variants with different gain ranges and complementary PNP types. The BC847CW specifically denotes the C gain binning option, providing higher current gain than A or B variants. It is designed for use in consumer electronics and portable devices requiring efficient signal processing.
Replacement Considerations
Direct replacements include other BC847C variants in compatible packages such as SOT23 or SOT363 if pinout alignment allows. Verify that substitute components meet the same 45 V VCEO and 100 mA IC specifications. Check thermal resistance values to ensure adequate heat dissipation in the new package style.
