Overview
The DTA123JU3HZGT106 is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors for simplified circuit design. It operates with a collector-emitter voltage of -50V and a continuous collector current of -100mA. The device includes an internal base resistor (R1) of 2.2kΩ and an emitter-base resistor (R2) of 47kΩ. Packaged in the SOT-323 (UMT3) surface-mount format, it supports a maximum power dissipation of 200mW and functions within a temperature range of -55°C to +150°C. This component holds AEC-Q101 qualification for automotive reliability.
Feature Summary
- Integrated bias resistors eliminate external components, reducing board space and assembly complexity.
- AEC-Q101 qualified for high reliability in automotive electronic applications.
- Compact SOT-323 package suitable for space-constrained surface-mount designs.
Applications
- Automotive logic interface circuits
- Battery management system switching
- General-purpose inverter circuits
Procurement Notes
Verify the complete part number including the suffix GT106 to ensure correct packaging configuration. Confirm AEC-Q101 compliance requirements against specific vehicle standards. Check supply status as this model may be subject to production lifecycle changes. Ensure storage conditions adhere to moisture sensitivity levels specified in the datasheet.
Selection Notes
Select this component when a PNP digital transistor with a 50V rating and 100mA current capacity is required. The 2.2kΩ input resistance suits standard logic level driving. Consider the SOT-323 footprint constraints during PCB layout. Verify thermal dissipation capabilities if operating near maximum temperature limits.
Part Context
This part belongs to the DTA123 series of pre-biased transistors from ROHM. It shares pinout compatibility with variants like DTA123JUA but differs in packaging and specific electrical tolerances. The JU3 designation indicates the UMT3/SOT-323 package type. It serves as a direct replacement for discrete resistor-transistor networks in switching applications.
Replacement Considerations
DTA123JU3HZG is listed as a similar level part with the same pinout and package. DTA123EU3HZGT106 offers identical specifications in the same UMT3 package. Verify exact resistor ratios and hFE ranges before substitution.
