DTA114TU3T106

Overview

The DTA114TU3T106 is a PNP digital transistor manufactured by ROHM Semiconductor, housed in the SOT-323 (UMT3) surface-mount package. It integrates bias resistors to simplify circuit design. Key electrical parameters include a collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. The device features a typical input resistance of 10 kOhms and a minimum DC current gain (hFE) of 100 at -1 mA and -5 V. It operates with a maximum frequency of 250 MHz and has a power dissipation rating of 200 mW. The emitter-base voltage (VEBO) is specified at -5 V, and the maximum operating temperature reaches +150 C.

Feature Summary

• Integrates built-in bias resistors to eliminate external components for inverter circuits.
• Provides simplified on/off control logic without requiring external input resistors.
• Designed for high-speed switching applications with a 250 MHz maximum operating frequency.

Applications

• Inverter circuits
• Interface drivers
• Digital logic switching

Procurement Notes

Verify the specific suffix T106 against the official datasheet to confirm reel packaging specifications and tape dimensions. Ensure compatibility with standard SMT reflow profiles and check for RoHS compliance status as indicated in the manufacturer's documentation before finalizing procurement orders.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required for space-constrained designs. The 10 kOhm input resistor value suits general-purpose logic interfacing. Verify that the -50 V voltage rating and -100 mA current capacity meet the specific load requirements of the target application circuit.

Part Context

This part belongs to the DTA114 series of Bias Resistor Built-in Transistors (BRBTs). It shares the same pinout and package dimensions as related variants like the DTA114TU3 and DTA114TU3HZG. The T106 suffix specifically denotes the taping quantity and packaging format used for automated assembly processes.

Replacement Considerations

The DTA114TU3 is listed as a similar level replacement with the same pinout and package. Verify that the electrical characteristics, particularly the hFE range and voltage ratings, match the original design requirements before substitution.
