DTC123YU3HZGT106

Overview

The DTC123YU3HZGT106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323 (UMT3) surface-mount package. It features built-in bias resistors with typical values of R1 = 2.2 kΩ and R2 = 10 kΩ. Key electrical specifications include a collector-emitter voltage (VCEO) of 50 V, a continuous collector current (IC) of 100 mA, and a power dissipation (PD) of 200 mW. The device supports a maximum operating frequency of 250 MHz and operates within a temperature range of -55°C to +150°C. It is qualified under the AEC-Q101 standard for automotive applications.

Feature Summary

Integrates internal bias resistors to simplify circuit design by eliminating external components.
Automotive-grade reliability compliant with AEC-Q101 standards for harsh environments.
High switching speed capability suitable for high-frequency digital signal processing.

Applications

Automotive electronic control units requiring robust NPN switching.
General-purpose digital logic interface circuits.
Level shifting between different voltage domains in embedded systems.

Procurement Notes

Verify the complete part number including the suffix GT106 to ensure correct packaging and tape-and-reel configuration. Confirm AEC-Q101 qualification status if automotive compliance is required. Check for end-of-life or obsolescence notices from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a compact NPN switch with integrated base resistance is needed. Ensure the 50V voltage rating and 100mA current capacity meet the load requirements. Verify that the SOT-323 footprint fits the PCB layout constraints and that the thermal dissipation limits are adequate for the application.

Part Context

This part belongs to the DTC123Y series of digital transistors from ROHM. It shares the same pinout and core functionality as the DTC123YUAFRA but offers updated packaging and automotive qualification. It serves as a modern replacement for legacy discrete resistor-transistor networks in space-constrained designs.

Replacement Considerations

The DTC123YUAFRA is a confirmed substitute with identical pinout and package dimensions. Verify that the older variant meets all functional requirements before substitution.
