Overview
The DTA124XMT2L is a PNP digital transistor manufactured by Rohm Semiconductor, featuring built-in bias resistors for simplified circuit design. It operates with a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes an internal base resistor (R1) of 22 kOhms and an emitter-base resistor (R2) of 47 kOhms, yielding a typical resistance ratio of 2.1. Key electrical parameters include a minimum DC current gain (hFE) of 68 at -5 V and -5 mA, a transition frequency of 250 MHz, and a maximum power dissipation of 150 mW. It is housed in a surface-mount SOT-723 package.
Feature Summary
- Integrates bias resistors to eliminate external input components
- Qualified for automotive applications under AEC-Q101 standards
- Designed for use in inverters, interfaces, and drivers
Applications
- Automotive inverter circuits
- Interface driver stages
- General-purpose switching applications
Procurement Notes
Verify the specific suffix MT2L against the target datasheet revision to ensure compatibility with the required packaging format and automotive grade specifications. Confirm that the SOT-723 footprint matches the PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this component when a PNP digital transistor with a 22k/47k resistor ratio is required for space-constrained designs. Ensure the -50V rating and -100mA current capacity meet the load requirements. Verify that the AEC-Q101 qualification aligns with the system's reliability standards.
Part Context
This part belongs to the DTx series of bias resistor built-in transistors from Rohm. It serves as the PNP counterpart to NPN variants like the DTC124XMT2L. The MT2L suffix typically denotes the specific tape-and-reel packaging configuration for automated assembly processes.
Replacement Considerations
Direct substitutes include other AEC-Q101 qualified PNP digital transistors with identical R1/R2 values and SOT-723 packaging. Verify pinout compatibility and thermal characteristics before substitution.
