DTA114GU3T106

Overview

The DTA114GU3T106 is a PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323 (UMT3) surface-mount package. It integrates bias resistors with a typical input resistance of 10 kOhms and a resistor ratio of 1. Key electrical ratings include a collector-emitter voltage (VCEO) of -50 V, continuous collector current of -100 mA, and power dissipation of 200 mW. The device supports a maximum operating frequency of 250 MHz and functions within a temperature range of -55°C to +150°C storage.

Feature Summary

• Integrates bias resistors directly with the transistor for simplified circuit design
• Utilizes compact SOT-323 surface-mount packaging for space-constrained applications
• Designed for high-speed switching operations up to 250 MHz

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and ensure the specific suffix matches required packaging formats such as cut tape or reel quantities. Cross-reference datasheet revisions to guarantee parameter consistency before integration into final designs.

Selection Notes

Select this PNP variant when negative logic control or pull-up configurations are required. Ensure the -50 V rating exceeds the system's maximum voltage swings. Verify that the 10 kOhm internal resistance aligns with the driving source capabilities and desired switching speeds compared to alternative resistor ratios.

Part Context

This component belongs to the DTA114 series of built-in resistor transistors. It serves as the PNP counterpart to the NPN DTC114G series. The GU3 suffix indicates the specific SOT-323 package type and taping configuration used for automated surface-mount assembly processes.

Replacement Considerations

The DTC114G series offers complementary NPN functionality. For identical PNP specifications in the same package, verify availability of standard DTA114 variants. Check pinout compatibility if substituting with other manufacturers' pre-biased transistors.
