BC850BW_R1_00001

Overview

The BC850BW_R1_00001 is a general-purpose NPN bipolar junction transistor manufactured by Panjit International Inc. It features a collector-emitter voltage (VCEO) of 45 V and a maximum continuous collector current (IC) of 100 mA. The device utilizes an epitaxial planar silicon construction housed in a compact SOT-23 surface-mount package. This component is designed for low-power amplification and switching applications within electronic circuits.

Feature Summary

• NPN epitaxial planar silicon construction
• General-purpose amplifier and switching capability
• Compact SOT-23 surface-mount packaging

Applications

• Low-power signal amplification
• General-purpose switching circuits
• Consumer electronics control logic

Procurement Notes

Verify the specific beta binning suffix 'B' against design requirements, as it dictates the minimum DC current gain range. Confirm the SOT-23 footprint compatibility with PCB layout constraints. Ensure RoHS compliance documentation aligns with regional regulatory standards for the intended market deployment.

Selection Notes

Select this component when a 45 V breakdown voltage and 100 mA current rating are sufficient for the application. Compare the B-bin hFE characteristics against circuit biasing needs to ensure adequate gain. Consider the SOT-23 thermal dissipation limits relative to the expected power load during operation.

Part Context

This part belongs to the BC850 series of NPN general-purpose transistors from Panjit. The series typically includes variants with different voltage ratings and current gains. The R1_00001 suffix indicates reel packaging, distinguishing it from cut-tape or tube distributions used in other supply chain channels.

Replacement Considerations

Cross-reference with BC850B or BC850C equivalents from other manufacturers if sourcing availability is constrained. Verify that substitute parts maintain identical pinout configurations and electrical parameters to prevent circuit modification.
