DTC114EUBTL

Overview

The DTC114EUBTL is an NPN digital transistor from the ROHM DTC114E series, housed in a UMT3F (SOT-323FL) surface-mount package. It integrates bias resistors R1 and R2, both rated at 10 kΩ, to simplify circuit design by eliminating external input components. The device supports a maximum collector current of 100 mA and a supply voltage of 50 V. Key electrical parameters include a minimum DC current gain (hFE) of 30 at 5 mA/5 V, a transition frequency of 250 MHz, and a power dissipation capacity of 200 mW. The output voltage is typically 100 mV under specified load conditions.

Feature Summary

• Integrates built-in biasing resistors (R1=R2=10kΩ) to enable inverter circuit configuration without external input resistors
• Simplifies circuit design by requiring only on/off condition settings for operation
• Provides high-speed switching capability with a transition frequency of 250 MHz

Applications

• Inverter circuits
• Interface applications
• Driver circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and taping specifications. Ensure compliance with RoHS directives and check for any lifecycle status changes such as NRND or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a compact SOT-323FL footprint is required for NPN digital switching applications. Consider the 200 mW power dissipation rating and 50 V collector-emitter voltage limits relative to the target operating environment. Verify that the integrated 10 kΩ resistor values align with the required input drive characteristics.

Part Context

This part belongs to the DTC114E series of Bias Resistor Built-in Transistors (BRBTs). The series offers complementary PNP types within the DTA114E lineup. The UMT3F package variant provides a smaller form factor compared to standard SOT-23 packages while maintaining similar electrical performance characteristics for general-purpose switching.

Replacement Considerations

Direct replacements must match the NPN polarity, 100 mA current rating, 50 V voltage rating, and 10 kΩ internal resistor configuration. Verify pinout compatibility and thermal dissipation requirements for equivalent packages.
