DTA143XMFHAT2L

Overview

The DTA143XMFHAT2L is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors for simplified circuit design. It operates with a collector-emitter voltage of -50V and a continuous collector current of -100mA. The device includes an input resistor (R1) of 4.7kΩ and an emitter-base resistor (R2) of 10kΩ, resulting in a typical resistance ratio of approximately 2.1. It supports AEC-Q101 automotive qualification standards and is housed in a VMT3 (SOT-723/SC-105AA) surface-mount package with three terminals. The maximum power dissipation is rated at 150mW, with an operating temperature range extending up to +150°C.

Feature Summary

• Integrated bias resistors eliminate external component requirements
• Automotive-grade reliability compliant with AEC-Q101 standards
• Compact SMD packaging suitable for space-constrained designs

Applications

• Automotive electronic control units
• General-purpose switching circuits
• Interface logic level translation

Procurement Notes

Verify the specific suffix 'T2L' against official ROHM documentation to confirm tape-and-reel quantity and packaging specifications. Ensure the component meets current RoHS directives and check for any end-of-life notices or recommended replacement parts before finalizing procurement plans.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is required for automotive or high-reliability applications. The 4.7kΩ input resistor value suits standard logic interfaces. Confirm that the SOT-723 footprint aligns with the PCB layout constraints and that the thermal dissipation capabilities meet the system's power requirements.

Part Context

This part belongs to the DTA143 series of digital transistors from ROHM, which are designed to replace discrete resistor-transistor combinations. The XMFH variant specifically denotes the VMT3 package code and AEC-Q101 qualification, distinguishing it from standard commercial grade counterparts like the DTA143ZE or DTA143ZU3.

Replacement Considerations

Official documentation indicates no direct substitute part numbers are listed for this specific variant. Designers should evaluate other AEC-Q101 qualified PNP digital transistors from ROHM or competitors if supply issues arise, ensuring pin compatibility and electrical parameter equivalence.
