DTC124TUAT106

Overview

The DTC124TUAT106 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 typical values of 22 kOhms for both R1 and R2. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, continuous collector current of 100 mA, and power dissipation of 200 mW. The device features a minimum DC current gain (hFE) of 100 at 1 mA and 5 V, with a maximum operating frequency of 250 MHz. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates built-in biasing resistors to simplify circuit design by eliminating the need for external input resistors.
• Enables direct configuration of inverter circuits without additional discrete components on the input side.
• Provides high-speed switching capabilities suitable for digital logic applications.

Applications

• Inverter circuits requiring simplified input stages
• Digital logic interface applications
• General-purpose switching in consumer electronics

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status via the specific datasheet revision. Ensure storage conditions adhere to moisture sensitivity levels if applicable. Validate that the SOT-323-3 footprint matches the target PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN digital transistor with 50V rating and 100mA current capacity is required. The integrated 22kOhm resistors are suitable for standard TTL/CMOS logic interfacing. Consider the SOT-323-3 package size constraints and thermal dissipation limits of 200mW during board layout planning.

Part Context

This part belongs to the DTC124TUA series of digital transistors from ROHM Semiconductor. It is specifically designed as a pre-biased transistor solution to reduce component count and assembly time in digital switching applications. The 'AT106' suffix typically denotes the tape and reel packaging format used for automated surface-mount assembly processes.

Replacement Considerations

DTC124EU3 offers similar specifications with recommended status for new designs. DTC124GUAT106 provides comparable performance in the same UMT3 package. Verify pinout compatibility and electrical parameter tolerances before substituting these alternatives in existing designs.
