DTA143EEFRATL

Overview

The DTA143EEFRATL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors within an EMT3 (SOT-416) surface-mount package. It operates with a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes input resistance R1 and emitter-base resistance R2, both typically rated at 4.7 kΩ. Key electrical parameters include a minimum DC current gain (hFE) of 30 at -10 mA and -5 V, a maximum operating frequency of 250 MHz, and power dissipation of 150 mW. It supports AEC-Q101 automotive standards and functions within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates bias resistors to simplify circuit design by eliminating external components for inverter configurations.
• Complies with AEC-Q101 automotive qualification standards for reliability in vehicle applications.
• Provides high-speed switching capabilities suitable for digital signal processing interfaces.

Applications

• Automotive electronic control units requiring qualified discrete components.
• Digital logic interface circuits for microcontroller output buffering.
• Inverter circuits in portable devices and consumer electronics.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure compliance with RoHS directives and check for any end-of-life notices or recommended new designations before finalizing procurement plans.

Selection Notes

Select this component when a PNP digital transistor with integrated 4.7 kΩ resistors is required in a compact SOT-416 footprint. Consider the -50 V rating and 100 mA current limit for load compatibility. Verify thermal management requirements given the 150 mW power dissipation constraint in the specified package.

Part Context

This part belongs to the DTA143 series of pre-biased transistors from ROHM Semiconductor. The series offers complementary NPN types, such as the DTC143 series, allowing for matched pairs in push-pull configurations. The EMT3 package provides a small form factor ideal for space-constrained printed circuit board layouts.

Replacement Considerations

The DTA143EU3HZGT106 is listed as a similar level replacement with the same pinout and package. Verify that the substitute meets all electrical parameter requirements, including hFE and voltage ratings, before implementation.
