DTC124XUAT106

Overview

The DTC124XUAT106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323 (UMT3) surface-mount package. It integrates biasing resistors with typical values of R1 at 22 kOhms and R2 at 47 kOhms, yielding a ratio of 2.1. The device supports a maximum collector current of 100 mA and a collector-emitter voltage of 50 V. Key electrical parameters include a minimum DC current gain (hFE) of 68 at 5 mA and 5 V, a transition frequency of 250 MHz, and power dissipation of 200 mW. The emitter-base voltage is rated at 2.5 V.

Feature Summary

Integrates built-in biasing resistors to simplify circuit design
Enables inverter configuration without external input resistors
Utilizes compact SOT-323 surface-mount packaging

Applications

Inverter circuits
Digital logic interfaces
Switching applications

Procurement Notes

Verify the obsolete status carefully before procurement. This component carries an NRND designation, indicating it is not recommended for new designs. While existing production may continue for legacy support, long-term supply stability is not guaranteed. Confirm availability through authorized channels and assess alternative sourcing options to mitigate future obsolescence risks.

Selection Notes

Select this part only for maintenance or replacement of existing designs where the specific resistor ratios and NPN polarity are required. Due to its NRND status, engineers should evaluate newer alternatives for any fresh development projects. Ensure the SOT-323 footprint and thermal characteristics align with the target PCB layout constraints.

Part Context

This component belongs to the DTC124XU series of digital transistors from ROHM Semiconductor. These devices are characterized by their pre-biased nature, combining a transistor with internal resistors to reduce board space and assembly steps. The specific suffix indicates the tape-and-reel packaging format used for automated surface-mount processing.
