DTA114EEBTL

Overview

The DTA114EEBTL is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an EMT3 (SOT-416) surface-mount package. It integrates biasing resistors with a typical base resistance (R1) of 10 kOhms and emitter-base resistance (R2) of 10 kOhms. The device supports a collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -50 mA. Key electrical parameters include a minimum DC current gain (hFE) of 30, a saturation voltage of 300 mV at specific test conditions, and a maximum power dissipation of 150 mW. It operates up to a transition frequency of 250 MHz and functions within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates built-in biasing resistors to simplify circuit design and reduce component count.
• Optimized for high-speed switching applications with a 250 MHz transition frequency.
• Automotive-grade reliability certified under AEC-Q101 standards.

Applications

• Inverter circuits requiring compact pre-biased solutions.
• Gate driver stages for power MOSFETs or IGBTs.
• Switching logic interfaces in automotive electronic control units.

Procurement Notes

Verify the specific suffix 'TL' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the AEC-Q101 qualification meets the specific reliability class needed for the target application environment. Ensure the EMT3 footprint matches the PCB land pattern dimensions precisely to avoid soldering defects during reflow.

Selection Notes

Select this component when a PNP configuration with integrated 10k/10k resistor ratios is required. The low saturation voltage of 300 mW ensures efficient switching performance. Consider the 150 mW power dissipation limit for thermal management in dense layouts. The SOT-416 package offers a balance between size and thermal capability for general-purpose digital switching tasks.

Part Context

This part belongs to the DTA114 series of digital transistors from ROHM, which are designed to replace discrete transistor-resistor combinations. The EMT3 package variant provides a small form factor suitable for space-constrained designs. The series is widely used in consumer electronics and industrial control systems where reliable switching and minimal external components are prioritized.

Replacement Considerations

DTA114EEBHZGTL is listed as a similar specification alternative with identical pinout and package characteristics. Verify that the substitute maintains the same AEC-Q101 certification and electrical parameters before implementation.
