DTA114TUAT106

Overview

The DTA114TUAT106 is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates with a collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. The device includes a typical input resistor (R1) of 10 kOhms and exhibits a minimum DC current gain (hFE) of 100 at -1 mA and -5 V. Packaged in an SOT-323-3 (UMT3) surface-mount format, it supports a maximum power dissipation of 200 mW and functions up to a maximum operating frequency of 250 MHz. The component is rated for operation at temperatures up to +150°C.

Feature Summary

• Integrates internal biasing resistors to eliminate the need for external input components, facilitating straightforward inverter circuit configuration.
• Provides high DC current gain to ensure reliable switching performance within digital logic applications.
• Utilizes a compact SMD package suitable for space-constrained surface-mount assembly processes.

Applications

• Inverter circuits requiring simplified input stages
• Digital logic interface buffering
• Switching applications in portable electronic devices

Procurement Notes

Verify the supply status carefully before integration, as this specific part number is classified as Not Recommended for New Designs (NRND). Confirm that existing inventory or last-time buy options meet project requirements. Ensure compatibility with the SOT-323-3 footprint during PCB layout finalization. Cross-reference ordering suffixes to match exact packaging specifications required for automated assembly lines.

Selection Notes

Select this component when a PNP digital transistor with a 50V rating and 100mA current capacity is required. The 10kOhm input resistance suits standard logic drive levels. Consider alternative active parts from the same series if NRND status restricts long-term availability. Verify thermal management capabilities given the 200mW power dissipation limit in the small outline package.

Part Context

This component belongs to the DTA114TUA series of PNP digital transistors. It shares pinout and functional characteristics with related variants such as DTA114TU3 and DTA114TU3HZG. These parts are designed for general-purpose switching and logic interfacing tasks where integrated biasing reduces component count and board space.

Replacement Considerations

DTA114TU3 and DTA114TU3HZG are confirmed substitutes with identical pinouts and packages. Verify electrical parameter equivalence against original design specifications before implementation.
