DTA023YUBTL

Overview

The DTA023YUBTL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors to simplify circuit design. It operates with a collector-emitter voltage of -50V and a continuous collector current of -100mA. The device incorporates an input resistance (R1) of 2.2kΩ and an emitter-base resistance (R2) of 10kΩ. Key electrical characteristics include a DC current gain (hFE) of at least 35 at 5mA/10V and a transition frequency of 250MHz. Power dissipation is rated at 150mW, with a maximum operating temperature of +150°C. It is housed in the EMT3F (SOT-416FL) surface-mount package.

Feature Summary

• Integrates biasing resistors to enable inverter circuit configuration without external components
• Provides high-speed switching capability with a 250MHz transition frequency
• Offers compact surface-mount packaging for space-constrained designs

Applications

• General-purpose switching circuits
• Inverter logic applications
• Driver circuits for low-current loads

Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as ROHM may offer alternative tape-and-reel configurations or updated revision codes. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation prior to procurement. Ensure the selected component matches the required polarity and resistor values for the intended application design.

Selection Notes

Select this component for PNP digital switching applications requiring integrated biasing. Compare the 2.2kΩ input resistance against other series members like DTA023YEBTL if different drive currents are needed. Verify that the 150mW power dissipation rating suffices for the thermal environment. Check compatibility with the EMT3F footprint during PCB layout planning.

Part Context

This part belongs to ROHM's standard digital transistor family, which combines bipolar junction transistors with internal resistors. These devices replace discrete transistor-resistor networks, reducing board space and assembly complexity. The DTA023YUBTL specifically addresses PNP requirements within this portfolio, offering a standardized solution for common logic interface tasks.

Replacement Considerations

DTA023YU3 is listed as a similar specification replacement with a UMT3 package. Verify pinout and electrical parameter equivalence before substitution.
