DTA144TUAT106

Overview

The DTA144TUAT106 is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323-3 (UMT3) surface-mount package. It integrates a built-in bias resistor with a typical value of 47 kOhms to simplify circuit design. The device supports a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. Key electrical characteristics include a minimum DC current gain (hFE) of 100 at -1 mA and -5 V, a maximum operating frequency of 250 MHz, and a power dissipation rating of 200 mW. The component operates within a temperature range up to +150 C.

Feature Summary

Integrates a 47 kOhm bias resistor to enable inverter circuit configuration without external input resistors
Simplifies circuit design by requiring only on/off condition settings for operation
Provides high-speed switching capability suitable for interface and driver applications

Applications

Inverter circuits
Interface circuits
Driver circuits

Procurement Notes

Verify the specific suffix AT106 against official datasheets to confirm packaging details such as reel or cut tape specifications. Ensure compatibility with surface mount assembly processes. Confirm RoHS compliance status through manufacturer documentation before procurement.

Selection Notes

Select this component when a PNP digital transistor with a 47 kOhm base resistor is required in a compact SOT-323 package. Consider the -50 V voltage rating and -100 mA current limit for load requirements. Verify that the 200 mW power dissipation meets thermal constraints in the target application environment.

Part Context

This part belongs to the ROHM DTx series of digital transistors, which are Bias Resistor Built-in Transistors (BRBTs). The DTA144TUA variant specifically denotes the PNP polarity and UMT3 package type within this family, offering a compact solution for replacing discrete resistor-transistor combinations.
