DTA114TU3HZGT106

Overview

The DTA114TU3HZGT106 is a PNP digital transistor manufactured by ROHM Semiconductor, housed in a UMT3 (SOT-323) surface-mount package. It integrates a single PNP bipolar junction transistor with built-in bias resistors to simplify circuit design. Key electrical specifications include a collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) of -100 mA. The device features a typical base input resistance (R1) of 10 kOhms and achieves a minimum DC current gain (hFE) of 100 at -1 mA and -5 V. It supports a maximum operating frequency of 250 MHz with a power dissipation rating of 200 mW and an extended maximum operating temperature of +150°C.

Feature Summary

• Integrates a PNP transistor with a 10 kOhm base resistor for simplified digital switching applications
• High thermal stability with a maximum operating temperature of +150°C
• Compact SMD form factor suitable for space-constrained designs

Applications

• General-purpose digital switching circuits
• Interface drivers between logic gates and loads
• Level shifting applications in low-voltage systems

Procurement Notes

Verify the specific suffix 'HZGT106' against the manufacturer's official datasheet to confirm the exact reel quantity and tape-and-reel specifications. Ensure that the ordering documentation matches the required automotive or industrial qualification standards if applicable. Cross-reference the component marking code on the physical device with the manufacturer's identification guide to prevent counterfeit substitution during assembly.

Selection Notes

Select this component when a PNP configuration with a 10 kOhm input resistance is required within a compact SOT-323 footprint. Consider the -50 V collector-emitter voltage limit and -100 mA current capacity for load requirements. Evaluate the 200 mW power dissipation capability against the expected thermal environment, noting the high +150°C operating temperature rating allows for robust performance in elevated heat conditions compared to standard commercial grades.

Part Context

This part belongs to the DTA114 series of pre-biased transistors from ROHM Semiconductor. The series offers various resistor ratios and polarities to accommodate different logic interface needs. The UMT3 package provides a small outline transistor solution ideal for modern high-density PCB layouts. This specific variant combines PNP polarity with a standard 10 kOhm base resistor value.

Replacement Considerations

Compatible substitutes include the DTA114TU3T106 and DTA114EU3HZGT106, which share identical pinouts and core electrical characteristics. Verify that alternative packages such as SOT-23 variants maintain compatibility with existing board footprints before implementation.
