DTC114WUAT106

Overview

The DTC114WUAT106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323-3 (UMT3) surface-mount package. It integrates bias resistors with a typical input resistance of 10 kOhms and a resistor ratio of 0.47. Key electrical parameters include a maximum collector-emitter voltage of 50 V, continuous collector current of 100 mA, and power dissipation of 200 mW. The device features a minimum DC current gain of 24 at 10 mA and 5 V, with a maximum operating frequency of 250 MHz. Additional ratings include a collector-emitter saturation voltage of 300 mV, emitter-base voltage of 3 V, and output voltage of 100 mV.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count.
• Optimized for high-speed switching applications with a maximum operating frequency of 250 MHz.
• Designed for low-voltage operation with specified saturation and output voltage characteristics.

Applications

• General-purpose switching circuits
• Interface driver stages
• Logic level translation

Procurement Notes

Verify the specific suffix 'UA' against the manufacturer's official datasheet to confirm it denotes the tape-and-reel packaging format rather than a functional variation. Ensure the ordering part number matches the required reel quantity of 3000 units. Cross-reference the RoHS compliance status directly with the latest product specification document before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN digital transistor with a 10 kOhm base resistor is required. The SOT-323 package suits space-constrained designs. Verify that the 50 V collector-emitter voltage rating meets the circuit requirements. Confirm the 200 mW power dissipation limit is sufficient for the intended thermal environment and duty cycle.

Part Context

This part belongs to the ROHM DTC114 series of Bias Resistor Built-in Transistors. It shares the same core transistor structure as the DTC114WU3 but differs in packaging configuration. The series is designed to replace discrete resistor-transistor combinations, offering a standardized solution for digital switching tasks in consumer and industrial electronics.

Replacement Considerations

The DTC114WU3T106 is a confirmed substitute part number within the same family, differing primarily in packaging type. Verify pinout compatibility and electrical parameter equivalence before substitution.
