DTA143TCAHZGT116

Overview

The DTA143TCAHZGT116 is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It integrates bias resistors with a typical input resistance of 4.7 kOhms and features a collector-emitter maximum voltage (VCEO) of -50 V. The device supports a continuous collector current of -100 mA and operates up to a maximum frequency of 250 MHz. With a power dissipation rating of 350 mW and a minimum DC current gain (hfe) of 100 at -1 mA and -5 V, it is qualified under AEC-Q101 standards for automotive applications.

Feature Summary

• Integrates built-in biasing resistors to simplify circuit design by eliminating the need for external input components.
• Qualified for automotive use under AEC-Q101 standards, ensuring high reliability for vehicle electronics.
• Designed for efficient switching in inverter, interface, and driver circuits within compact surface-mount configurations.

Applications

• Inverter circuits
• Interface circuits
• Driver circuits

Procurement Notes

Verify the complete part number including the suffix to ensure correct packaging configuration, as variants exist for reel, cut tape, and MouseReel formats. Confirm AEC-Q101 qualification status if automotive grade compliance is required for the specific application environment. Cross-reference the manufacturer datasheet for thermal derating curves and soldering profile recommendations to maintain component integrity during assembly processes.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is required for space-constrained designs. Ensure the -50 V collector-emitter voltage rating aligns with the system's supply rails. Verify that the 4.7 kOhm input resistance matches the driving source impedance requirements. Consider the SOT-23-3 footprint constraints and thermal management needs given the 350 mW power dissipation limit in the final enclosure.

Part Context

This part belongs to the ROHM DTA series of pre-biased transistors, which combine NPN or PNP transistors with internal resistors. The 'HZG' suffix typically denotes specific packaging and automotive qualification attributes within the ROHM portfolio. It serves as a complementary counterpart to NPN digital transistors like the DTC143 series, providing balanced options for push-pull or differential signaling applications in electronic control units.

Replacement Considerations

Direct substitutes include other ROHM PNP digital transistors with similar electrical characteristics, such as the DTA143XCAHZG or DTA143ECAHZG, provided the resistor ratios and voltage ratings are compatible. Verify pinout compatibility and thermal performance before substituting with non-ROHM equivalents to ensure circuit functionality remains unaffected.
