MBT3946

Overview

The MBT3946 is a dual bipolar junction transistor (BJT) manufactured by Shenzhen Slkormicro Semicon Co., Ltd. It integrates one NPN and one PNP transistor within a single SOT-363 surface-mount package. The device supports a maximum collector current of 200 mA and withstands a collector-emitter breakdown voltage of 40 V. Key electrical characteristics include a transition frequency of 300 MHz and a power dissipation rating of 350 mW. The component operates reliably across an extended temperature range from -55°C to +150°C, making it suitable for compact circuit designs requiring complementary switching or amplification.

Feature Summary

Integrates complementary NPN and PNP transistors in a single compact package
Supports high-speed signal processing with a 300 MHz transition frequency
Provides robust thermal performance with operation up to 150°C

Applications

Complementary switching circuits
Small-signal amplification stages
General-purpose digital logic interfacing

Procurement Notes

Verify the manufacturer designation on the component marking against Shenzhen Slkormicro Semicon Co., Ltd. specifications. Confirm the package type is SOT-363 and check for RoHS compliance documentation. Ensure the part number matches the exact dual BJT configuration rather than single-transistor variants.

Selection Notes

Select this component when space constraints require two matched transistors in one footprint. Compare the 200 mA current limit and 40 V voltage rating against circuit requirements. Consider the 350 mW power dissipation capability for thermal management planning in dense PCB layouts.

Part Context

This part belongs to the family of small-signal dual transistors designed for surface-mount technology. It serves as a functional alternative to standard discrete pairs, reducing board space and assembly steps. The SOT-363 housing allows for automated placement in high-volume manufacturing environments.
