DTA143EMFHAT2L

Overview

The DTA143EMFHAT2L is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors for simplified circuit design. It operates with a collector current of 100 mA and a transition frequency of 250 MHz. The device is housed in a VMT3 (SOT-723) surface-mount package with dimensions of 1.2x1.2 mm. Key electrical parameters include a maximum collector-emitter voltage of -50 V, power dissipation of 150 mW, and an input resistance (R1) of 47 kOhms. It meets AEC-Q101 automotive grade standards.

Feature Summary

• Integrated bias resistors eliminate the need for external input components, enabling straightforward inverter circuit configuration.
• Automotive-grade qualification ensures reliability under strict environmental and operational conditions defined by AEC-Q101.
• Compact SOT-723 packaging supports high-density surface-mount assembly in space-constrained applications.

Applications

• Automotive electronic systems requiring robust switching capabilities
• General-purpose inverter circuits in consumer electronics
• Interface logic level shifting in embedded control units

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific ordering suffixes that may indicate tape-and-reel quantities versus cut-tape options. Ensure storage conditions adhere to moisture sensitivity level requirements prior to soldering.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is required for automotive or industrial applications. Compare R1 values against existing designs to ensure compatibility with driving source impedance. Verify that the VMT3 package footprint matches the target PCB layout constraints.

Part Context

This part belongs to the DTA143 series of pre-biased transistors from ROHM. It serves as the PNP counterpart to NPN variants like the DTC143 series. The EMFHAT2L suffix denotes the specific VMT3 package and automotive-grade qualification, distinguishing it from standard commercial grades.

Replacement Considerations

Direct substitutes include other PNP digital transistors in SOT-723 packages with similar R1/R2 ratios and voltage ratings. Verify pinout compatibility and thermal characteristics before substitution. Cross-reference with ROHM's complementary NPN types if system symmetry is required.
