DTC144EEFRATL

Overview

The DTC144EEFRATL is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-416 (EMT3) surface-mount package. It integrates built-in bias resistors with a typical ratio of 1, featuring a 47 kOhm input resistance. Key electrical parameters include a collector continuous current of 100 mA, power dissipation of 150 mW, and a minimum DC current gain (hFE) of 68 at 5 mA and 5 V. The device supports a maximum operating temperature of +150 C and has an output voltage of 100 mV.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design by eliminating the need for external input components.
• Features a compact SOT-416 surface-mount package suitable for space-constrained applications.
• Designed for high-temperature operation with a maximum junction temperature rating of +150 C.

Applications

• Inverter circuits
• Interface logic drivers
• General-purpose switching applications

Procurement Notes

Verify the specific suffix FRATL against the official ROHM datasheet to confirm packaging details and availability status. Ensure compliance with RoHS directives and check for AEC-Q qualification requirements if automotive use is intended. Confirm lead times and lifecycle status directly with authorized distributors as supply chain conditions may vary.

Selection Notes

Select this component when a single NPN digital transistor with 47 kOhm base resistance is required. Verify that the 100 mA collector current and 150 mW power dissipation meet the load requirements. Ensure the SOT-416 package footprint matches the PCB layout constraints and that the operating temperature range aligns with the system environment.

Part Context

This part belongs to the DTC144 series of digital transistors from ROHM Semiconductor. The series typically includes complementary PNP types such as the DTA144EE. These devices are designed to replace discrete resistor-transistor combinations, offering reduced board space and simplified assembly processes for standard logic interface tasks.

Replacement Considerations

Check for direct pin-compatible alternatives within the same series or from other manufacturers. Verify that any substitute maintains the 47 kOhm resistor ratio, 100 mA current rating, and SOT-416 package dimensions to ensure mechanical and electrical compatibility without redesigning the host circuit.
