Overview
The DTA143EUBHZGTL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors within an SMD/SMT surface-mount package. It operates with a collector-emitter voltage of -50V and a continuous collector current of -100mA. The device includes an input resistor (R1) of 4.7 kOhms and an emitter-base resistor (R2) of 4.7 kOhms. Key electrical parameters include a DC current gain (hFE) of 30 to 100 at -10mA/-5V, a maximum operating frequency of 250 MHz, and power dissipation of 200 mW. It supports a maximum operating temperature of +150°C and complies with AEC-Q101 automotive standards.
Feature Summary
- Integrates biasing resistors to simplify circuit design and reduce component count
- Automotive-grade reliability compliant with AEC-Q101 standards
- High-speed switching capability suitable for high-frequency applications
Applications
- Automotive electronic control units requiring robust switching components
- General-purpose digital logic interface circuits
- Power management systems utilizing pre-biased transistor arrays
Procurement Notes
Verify the specific ordering suffix and tape-and-reel quantity against official ROHM documentation before procurement. Confirm that the component status aligns with current design requirements, as availability may vary based on production lifecycle stages. Ensure compatibility with existing supply chain protocols for automotive-grade semiconductors.
Selection Notes
Select this component when a PNP digital transistor with equal R1/R2 ratios is required in a compact SOT-323FL package. Consider its -50V rating and 100mA current capacity for low-power switching tasks. Verify thermal management needs given the 200mW dissipation limit and ensure the application environment meets AEC-Q101 qualification criteria.
Part Context
This part belongs to the DTA143 series of PNP digital transistors from ROHM Semiconductor. It shares functional similarities with other variants like DTA143EU3HZGT106 but differs in packaging and specific resistor configurations. The series is designed for applications requiring integrated biasing solutions in small form factors.
Replacement Considerations
DTA143EU3HZGT106 is listed as a recommended replacement with the same pinout and package type. Verify electrical parameter equivalence, particularly regarding hFE ranges and saturation voltages, before substituting.
