BC849BW

Overview

The BC849BW is an NPN general-purpose transistor manufactured by Diotec Semiconductor, housed in a SOT-323 surface-mount package. It features a maximum collector current of 100 mA and a collector-emitter voltage rating of 30 V. The device belongs to the Group C current gain category, offering a DC current gain range from 420 to 800 at IC = 2 mA and VCE = 5 V. Power dissipation is rated at 200 mW, with a junction temperature range spanning -55°C to +150°C.

Feature Summary

Designed for universal application as a general-purpose switching and amplification component
Features three distinct current gain groups to accommodate varied circuit requirements
Compliant with RoHS directives without exemptions and adheres to REACH regulations

Applications

Signal processing circuits
Electronic switching applications
Amplification stages

Procurement Notes

Verify that the ordering suffix 'BW' corresponds to the specific commercial grade and gain group (Group C) required for your design. Confirm compliance with AEC-Q101 standards if automotive reliability is necessary, as this variant represents standard commercial/industrial grade performance. Ensure the selected packaging matches production volume needs.

Selection Notes

Select this component when a low-voltage NPN transistor with high current gain is needed for compact designs. The SOT-323 package suits space-constrained PCB layouts. Consider the 30 V collector-emitter voltage limit and 100 mA continuous current capability against load requirements. Evaluate thermal resistance characteristics for heat dissipation management in enclosed environments.

Part Context

This part belongs to the BC846W through BC849CW series of SMD general-purpose NPN transistors. The series offers complementary PNP options and varies primarily by voltage ratings and gain groupings. The BC849W specifically targets lower voltage applications compared to the BC846W or BC847W variants within the same family.
