Overview
The BC847B/SNR is a single NPN bipolar junction transistor manufactured by Nexperia. It utilizes silicon technology and is housed in an SOT-23 (TO-236AB) surface-mount package. The device supports a maximum DC collector current of 100 mA and offers a collector-emitter voltage rating of 45 V, with a collector-base voltage of 50 V and emitter-base voltage of 6 V. Power dissipation is rated at 250 mW, and the gain-bandwidth product reaches 100 MHz. The component operates within a temperature range of -65°C to +150°C.
Feature Summary
- Single NPN configuration for compact circuit integration
- Low collector capacitance for efficient signal handling
- Low collector-emitter saturation voltage for reduced power loss
- Small SMD plastic package design
Applications
- General-purpose switching applications
- Amplifier circuits
- Driver stages for low-power loads
Procurement Notes
Verify the specific suffix SNR against official Nexperia documentation to confirm tape-and-reel specifications and lot traceability requirements. Ensure the ordering part number matches the exact package variant and marking code required for your assembly process. Cross-reference with authorized distributors to validate current availability and authenticity before finalizing procurement plans.
Selection Notes
Select this component when a single NPN transistor with moderate voltage ratings and high current gain is required in a small footprint. It serves as a general-purpose solution for switching and amplification tasks where board space is limited. Consider the 100 mA current limit and 250 mW power dissipation capabilities during thermal management planning for the target application environment.
Part Context
This component belongs to the BC847 series of general-purpose NPN transistors from Nexperia. The series is widely used in consumer electronics and industrial equipment due to its reliability and small form factor. The BC847B variant specifically denotes a particular DC current gain binning level within the standard product line.
Replacement Considerations
Direct replacements include other BC847B variants from different manufacturers or Nexperia packages such as BC847B-QR for automotive contexts. Verify pinout compatibility and electrical parameter overlaps before substitution.
