DTC143XU3HZGT106

Overview

The DTC143XU3HZGT106 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 = 4.7 kΩ and R2 = 10 kΩ to simplify circuit design. Key electrical specifications include a collector-emitter voltage (VCEO) of 50 V, a continuous collector current (Ic) of 100 mA, and a DC current gain (hFE) minimum of 30 at 10 mA and 5 V. The device features a maximum operating frequency of 250 MHz, power dissipation of 200 mW, and an emitter-base voltage (VEBO) of 2.5 V. It is qualified under AEC-Q101 standards for automotive applications.

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer confirmation. Ensure the ordering suffix matches the required tape-and-reel quantity of 3000 units. Confirm RoHS compliance status and specific automotive qualification documentation prior to integration into safety-critical systems.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for space-constrained designs. The SOT-323 package offers a small footprint suitable for high-density PCB layouts. Consider the complementary PNP variant, DTA143XU3HZG, if a negative polarity configuration is needed for the same application architecture.

Part Context

This part belongs to the DTC143 series of bias-resistor-built-in transistors from ROHM Semiconductor. The series is designed for general-purpose switching and logic inversion tasks. The UMT3 package code corresponds to the industry-standard SOT-323 form factor, ensuring compatibility with existing footprints used across various discrete semiconductor applications.

Replacement Considerations

The DTC143EU3HZG is listed as a similar level replacement with the same pinout and package. Verify that the specific resistor ratios and hFE characteristics of the substitute meet the original circuit requirements before implementation.
