Overview
The DTA123JMFHAT2L is a PNP digital transistor with built-in resistors, manufactured by Rohm Semiconductor. It features an integrated base resistor (R1) of 2.2 kOhms and an emitter-base resistor (R2) of 47 kOhms. The device supports a maximum collector current of 100 mA and a collector-emitter voltage of -50 V. Key electrical parameters include a DC current gain (hFE) of at least 80 at 10 mA and 5 V, and a transition frequency of 250 MHz. Power dissipation is rated at 150 mW, with a saturation voltage of 300 mV at specific test conditions. It is housed in the VMT3 (SOT-723) surface-mount package and holds AEC-Q101 automotive qualification.
Feature Summary
- Integrates biasing resistors to simplify circuit design and reduce component count
- Automotive-grade reliability certified under AEC-Q101 standards
- Compact SMD footprint suitable for space-constrained applications
Applications
- Automotive electronic control units requiring signal inversion or level shifting
- Driver circuits for low-current loads in vehicle systems
- Logic interface buffers between microcontrollers and peripheral devices
Procurement Notes
Verify the exact ordering suffix against the manufacturer's official datasheet to ensure correct packaging and specifications. Confirm that the component meets the required automotive grade certification if used in safety-critical systems. Check for any obsolescence notices or recommended replacement parts before finalizing procurement plans.
Selection Notes
Select this component when a PNP digital transistor with specific 2.2k/47k resistor ratios is required. Ensure the operating voltage does not exceed -50 V and the current remains within 100 mA limits. Consider the VMT3 package dimensions for PCB layout compatibility and verify thermal dissipation requirements for the intended application environment.
Part Context
This part belongs to the DTA123 series of pre-biased transistors from Rohm. It is designed as a drop-in replacement for discrete resistor-transistor networks. The JMFHA suffix indicates specific manufacturing and packaging details consistent with automotive-grade production lines.
Replacement Considerations
Check for direct substitutes like DTA123EMT2L for non-automotive applications or DTA123JM for similar performance without automotive certification. Verify pinout compatibility and electrical parameter overlaps before substitution.
