DTA115TU3T106

Overview

The DTA115TU3T106 is a single PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors in an SOT-323 (UMT3) surface-mount package. It operates with a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes a typical input resistance of 100 kOhms and achieves a minimum DC current gain of 100 at -1 mA and -5 V. It supports a maximum operating frequency of 250 MHz with power dissipation rated at 200 mW and a maximum operating temperature of +150 C.

Feature Summary

• Integrates a 100 kOhm bias resistor to eliminate external components for inverter circuit configuration
• Simplifies circuit design by requiring only on/off condition settings for operation
• Provides complementary NPN functionality within the DTC115T series family

Applications

• Inverter circuits
• Interface applications
• Driver circuits

Procurement Notes

Verify the specific suffix T106 against official datasheets to confirm reel packaging and quantity specifications. Confirm RoHS compliance status through manufacturer documentation before integration. Ensure the component meets automotive restrictions as it is designated for standard-grade use rather than automotive equipment.

Selection Notes

Select this PNP variant when a high input impedance of 100 kOhms is required for logic interfacing. Compare against the DTC115T series if an NPN polarity is needed for complementary designs. Verify that the SOT-323 footprint aligns with existing PCB layouts and thermal management requirements for 200 mW dissipation.

Part Context

This component belongs to the DTA115TUA series of Bias Resistor Built-in Transistors. It shares the UMT3 package code and functional architecture with other members of the DTA11xTU3 family, differing primarily in internal resistance values and specific suffix designations for packaging or testing variations.
