DTC124XU3HZGT106

Overview

The DTC124XU3HZGT106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323 (UMT3) surface-mount package. It integrates bias resistors with typical values of R1 = 22 kΩ and R2 = 47 kΩ. The device supports a supply voltage of 50 V and a continuous collector current of 100 mA. Key electrical parameters include a minimum DC current gain (hFE) of 68 at 5 mA/5 V, a transition frequency of 250 MHz, and a power dissipation rating of 200 mW. It meets AEC-Q101 automotive qualification standards.

Feature Summary

• Integrates built-in biasing resistors to simplify circuit design by eliminating the need for external input resistors.
• Qualified for automotive applications under the AEC-Q101 standard for high reliability.
• Provides complementary PNP type availability within the same series.

Applications

• Inverter circuits requiring simplified input configurations.
• Automotive electronic systems demanding qualified discrete components.
• General-purpose switching applications in consumer electronics.

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm that the specific ordering suffix matches the required packaging format and tape specifications. Ensure compliance with RoHS directives and check for any obsolescence notices regarding long-term supply commitments before finalizing procurement plans.

Selection Notes

Select this component when a single NPN configuration with integrated biasing is required for space-constrained designs. The SOT-323 package offers a compact footprint suitable for dense PCB layouts. Consider the complementary DTA124XU3HZG if a PNP polarity is needed for the same resistor values and package constraints.

Part Context

This part belongs to the DTC124 series of digital transistors from ROHM Semiconductor. The series features various resistor combinations and packages, with the XU3 variant specifically denoting the SOT-323 form factor. The GT106 suffix indicates the specific taping quantity and reel configuration used for automated assembly processes.

Replacement Considerations

The DTC124XUAFRA is listed as a similar level replacement with the same pinout and package, though it is not recommended for new designs. Verify exact parameter matching for R1, R2, and hFE when substituting.
