DTC115EUAT106

Overview

The DTC115EUAT106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323-3 surface-mount package. It integrates bias resistors with a typical input resistance (R1) of 100 kOhms and a resistor ratio of 1. 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 82 at 5 mA and 5 V, with a maximum operating frequency of 250 MHz. It operates within a temperature range up to +150°C.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count.
• Provides high-speed switching capability suitable for applications requiring frequencies up to 250 MHz.
• Offers compact surface-mount packaging for efficient space utilization on printed circuit boards.

Applications

• General-purpose switching circuits
• Driver circuits for logic interfaces
• Level shifting applications

Procurement Notes

Verify the supply status before procurement as this component is designated as Not Recommended for New Designs (NRND). Confirm that the ordering suffix matches the required tape and reel quantity. Ensure compatibility with existing designs rather than initiating new projects with this part number.

Selection Notes

Select this component when a single NPN digital transistor with 100 kOhm input resistance is required in an SOT-323 package. Consider the 50 V collector-emitter voltage rating and 100 mA current capacity against load requirements. Verify thermal management needs given the 200 mW power dissipation limit.

Part Context

This part belongs to the DTC115EUA series of NPN digital transistors. It shares pinout and package characteristics with related variants such as the DTC115EU3. The series is characterized by integrated bias resistors and small-signal switching capabilities.

Replacement Considerations

The DTC115EU3T106 is listed as a similar level part with the same pinout and package. Verify functional equivalence and supply status before substitution.
