DTC114EU3T106

Overview

The DTC114EU3T106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in a surface-mount SOT-323 (UMT3) package. It integrates bias resistors to simplify circuit design without external components. Key electrical specifications include a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device features a typical input resistance (R1) of 10 kOhms and an emitter-base resistance (R2) of 10 kOhms. It offers a minimum DC current gain (hFE) of 30 at 5 mA and 5 V, with a maximum operating frequency of 250 MHz. Power dissipation is rated at 200 mW, and the saturation voltage is 300 mV under specified conditions.

Feature Summary

• Integrates built-in bias resistors to eliminate the need for external input resistors in inverter circuits.
• Provides high-speed switching capabilities suitable for applications requiring frequencies up to 250 MHz.
• Utilizes a compact SOT-323 surface-mount package designed for space-constrained PCB layouts.

Applications

• General-purpose inverter circuits
• Driver circuits for relays and solenoids
• Switching applications in portable electronic devices

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, such as tape and reel quantities. Confirm RoHS compliance status through official documentation before integration. Check long-term supply plans to ensure availability for production cycles. Validate that the component meets the required storage temperature ranges for your specific environment.

Selection Notes

Select this component when a single NPN digital transistor with 50 V rating and 100 mA current capacity is required. Ensure the 10 kOhm input resistance matches the driving source impedance. Consider the SOT-323 package dimensions for board space constraints. Verify that the 200 mW power dissipation rating is sufficient for the thermal management strategy.

Part Context

This part belongs to the DTC114 series of digital transistors from ROHM Semiconductor. The series is characterized by built-in bias resistors and is widely used in standard-level consumer electronics. The EU3 suffix indicates the specific pinout and resistor values within the SOT-323 package family.

Replacement Considerations

DTC114EU3HZGT106 is a recommended replacement with the same pinout and package. Both parts share identical electrical characteristics and are AEC-Q101 qualified. Verify compatibility with existing PCB footprints and circuit parameters before substitution.
