DTA043XMT2L

Overview

The DTA043XMT2L is a single PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors within a VMT-3 (SOT-723) surface-mount package. It operates with a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes an input resistor (R1) of 4.7 kOhms and an emitter-base resistor (R2) of 10 kOhms, yielding a typical resistance ratio of 2.1. Key electrical parameters include a minimum DC current gain (hFE) of 35 at -5 mA and -10 V, a transition frequency of 250 MHz, and a power dissipation rating of 150 mW. The component supports a maximum operating temperature of +150°C.

Feature Summary

• Integrates thin-film bias resistors for simplified inverter circuit configuration without external components.
• Provides complete isolation between bias resistors to enable negative input biasing.
• Eliminates parasitic effects through integrated resistor design.

Applications

• Inverter circuits requiring simplified input stage design
• General-purpose switching applications in consumer electronics
• Interface circuits for microcontrollers and logic gates

Procurement Notes

Verify the NRND status before integration, as this indicates the component is not recommended for new designs. Confirm RoHS compliance details via official documentation. Ensure supply chain stability due to potential end-of-life constraints. Validate package compatibility with existing PCB footprints. Review latest datasheet revisions for any parameter updates prior to final procurement decisions.

Selection Notes

Select this component for applications requiring a compact PNP digital solution with integrated biasing. Compare against complementary NPN types like the DTD543XMT2L for push-pull configurations. Consider the 150 mW power dissipation limit for thermal management. Verify that the -50 V voltage rating meets system requirements. Check if the SOT-723 package dimensions fit the mechanical constraints.

Part Context

This part belongs to the DTA043XM series of standard-grade digital transistors from ROHM Semiconductor. It is designed for general-purpose use but is explicitly noted as not recommended for automotive equipment. The series offers complementary PNP types and utilizes thin-film technology for internal resistors. It serves as a cost-effective alternative to discrete resistor-transistor networks in space-constrained designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Designers should consult official ROHM documentation or distributor databases for qualified alternatives. Cross-referencing pinouts and electrical characteristics is essential when evaluating potential replacements.
