DTC114EETL

Overview

The DTC114EETL is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-416 (EMT3) surface-mount package. It integrates bias resistors with a typical ratio of 1:1, featuring R1 and R2 values of 10 kOhms each. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, continuous collector current of 100 mA, and power dissipation of 150 mW. The device offers a minimum DC current gain (hFE) of 30 at 5 mA/5 V, a transition frequency of 250 MHz, and operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates dual bias resistors with a 1:1 ratio for simplified circuit design
• Provides high-speed switching capability with a 250 MHz transition frequency
• Features low saturation voltage for efficient power handling
• Designed for compact surface-mount applications in the SOT-416 package

Applications

• Inverter circuits
• Interface logic drivers
• General-purpose driver applications

Procurement Notes

Verify the specific suffix 'ETL' confirms the tape-and-reel packaging format and 3000-unit quantity. Confirm RoHS compliance status through the manufacturer's latest documentation. Ensure the ordering part number matches the exact resistor configuration and polarity required for the target design.

Selection Notes

Select this component when a single NPN digital transistor with equal base and emitter resistors is required. The 10 kOhm resistor values suit standard logic interface levels. Consider the 150 mW power dissipation limit and SOT-416 thermal characteristics for the specific PCB layout constraints.

Part Context

This part belongs to the DTC114EE series of Bias Resistor Built-in Transistors (BRT). It is distinct from variants like DTC114YETL or DTC114TETL due to its specific internal resistor network configuration and hFE grading. The EMT3 package code corresponds to the SOT-416 form factor used for space-saving designs.

Replacement Considerations

Direct substitutes within the same family include DTC114EE without the reel suffix if loose components are acceptable. Verify equivalent NPN BRT devices with matching 10kΩ/10kΩ resistor ratios and 50V VCEO ratings from other manufacturers if sourcing changes are necessary.
