DTA114TCAHZGT116

Overview

The DTA114TCAHZGT116 is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It integrates bias resistors with a typical input resistance of 10 kOhms. The device supports a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. Key electrical specifications include a minimum DC current gain (hFE) of 100 at -1 mA and -5 V, a maximum operating frequency of 250 MHz, and a power dissipation rating of 200 mW. It operates up to +150°C and holds AEC-Q101 automotive qualification.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design
• Automotive-grade reliability certified under AEC-Q101 standards
• High switching speed capability for high-frequency applications

Applications

• Automotive electronic control units
• General-purpose digital switching circuits
• Interface drivers for microcontrollers

Procurement Notes

Verify the specific suffix GT116 against official ROHM documentation to confirm packaging type and reel specifications. Ensure compatibility with AEC-Q101 requirements if used in automotive contexts. Cross-reference datasheet revisions to validate parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is required in a compact SOT-23-3 footprint. Consider the 10 kOhm input resistance value for base drive calculations. Verify that the -50 V voltage rating and -100 mA current capacity meet the specific load requirements of the target application circuit.

Part Context

This part belongs to the DTx series of digital transistors from ROHM Semiconductor. These devices combine bipolar junction transistors with internal resistor networks to replace multiple discrete components. The DTA prefix indicates a PNP configuration, distinguishing it from NPN variants within the same product family.

Replacement Considerations

Check for direct substitutes such as DTC114TCAHZGT116 only if polarity inversion is acceptable. Verify pinout compatibility and thermal characteristics before substituting with other manufacturers' PNP digital transistors in the SOT-23-3 package.
