DTA113ZU3T106

Overview

The DTA113ZU3T106 is a PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323 (UMT3) surface-mount package. It integrates bias resistors with typical values of R1 = 1 kΩ and R2 = 10 kΩ. The device supports a collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) of -100 mA. Key electrical parameters include a minimum DC current gain (hFE) of 33 at -5 mA and -5 V, a transition frequency (fT) of 250 MHz, and a maximum power dissipation (Pd) of 200 mW. The saturation voltage (VCE(sat)) is specified at -300 mV under standard test conditions.

Feature Summary

• Integrates built-in biasing resistors to simplify circuit design by eliminating the need for external input resistors.
• Capable of forming inverter circuits directly without additional discrete components on the input side.
• Optimized for high-speed switching applications with a transition frequency of 250 MHz.

Applications

• Inverter circuits in digital logic systems
• Driver circuits for small-signal switching
• Interface circuits between microcontrollers and peripheral devices

Procurement Notes

Verify the specific ordering suffix T106 to confirm the tape-and-reel packaging format and quantity per reel. Ensure compatibility with SOT-323 footprint requirements during PCB layout. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated products.

Selection Notes

Select this component when a PNP configuration with low input resistance (1 kΩ) is required for direct logic interfacing. Compare against DTA114 variants if higher input impedance is needed. Verify that the 200 mW power dissipation rating meets thermal constraints within the target SOT-323 enclosure.

Part Context

This part belongs to the DTA113 series of Bias Resistor Built-in Transistors (BRBTs). It shares the same internal resistor network topology as the DTC113ZU3 but utilizes PNP polarity instead of NPN. The UMT3 package designation corresponds to the industry-standard SOT-323 form factor used in compact consumer electronics.

Replacement Considerations

The DTA113ZUB is listed as a similar specification part but is marked as not recommended for new designs. The DTA113ZE3TL offers identical electrical characteristics but uses an SOT-416 package, requiring footprint adaptation.
