Overview
DTA143TMFHAT2L is a PNP digital transistor with built-in resistors, manufactured by ROHM Semiconductor. It operates with a supply voltage of -50V and a collector current of -0.1A. The device features an input resistance (R1) ranging from 1kΩ to 4.7kΩ and an emitter-base resistance (R2) from 1kΩ to 47kΩ. Power dissipation is rated at 0.15W. It utilizes the VMT3 package (SOT-723/SC-105AA), measuring 1.2x1.2mm with a thickness of 0.55mm. The component supports AEC-Q101 standards for automotive applications.
Feature Summary
- Built-in bias resistors enable inverter circuit configuration without external input resistors.
- Thin-film resistors provide complete isolation, allowing positive input biasing and minimizing parasitic effects.
- Automotive-grade qualification ensures reliability under strict environmental conditions.
Applications
- Inverter circuits
- Interface logic level shifting
- Driver stages for low-power loads
Procurement Notes
Verify the specific suffix 'T2L' against official ROHM documentation to confirm tape-and-reel specifications and lot traceability. Confirm RoHS compliance status and ensure the component meets AEC-Q101 requirements if used in automotive designs. Check for obsolescence notices as some DTA143 variants are marked not recommended for new designs.
Selection Notes
Select this component when a compact PNP digital transistor with integrated biasing is required for space-constrained designs. The VMT3 package offers a small footprint suitable for high-density PCB layouts. Ensure the input resistance values align with the driving source impedance and desired switching speed for the target application.
Part Context
The DTA143 series comprises pre-biased transistors designed to simplify circuit design by integrating bias resistors. This specific variant belongs to the automotive-grade subset, adhering to AEC-Q101 standards. It serves as a direct replacement for discrete resistor-transistor combinations in signal inversion and buffering roles.
Replacement Considerations
Check for equivalent parts such as DTA143ZMFHA or DTA143ZMT2L, ensuring package compatibility (VMT3/SOT-723) and electrical parameter matching. Verify that substitute components also meet AEC-Q101 requirements if automotive qualification is necessary.
