DTA123JUBHZGTL

Overview

The DTA123JUBHZGTL is a PNP pre-biased digital transistor manufactured by Rohm Semiconductor, designed for surface-mount applications. It integrates biasing resistors within a UMT3F package (SOT-323FL), measuring 2.1x2.0 mm with a thickness of 1.05 mm. The device supports a collector current of 100 mA and operates at a maximum frequency of 250 MHz. Key electrical parameters include a power dissipation of 200 mW, an input resistance (R1) of 2.2 kΩ, and an emitter-base resistance (R2) of 47 kΩ. It holds AEC-Q101 automotive grade certification but is marked as not recommended for new designs.

Feature Summary

• Integrates built-in biasing resistors to simplify circuit design without external components
• Automotive-grade reliability certified under AEC-Q101 standards
• Compact UMT3F surface-mount package suitable for space-constrained layouts

Applications

• Automotive interface circuits
• Driver circuits requiring compact switching solutions
• Inverter control logic

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required packaging format. Check current supply status as this model is designated for existing customers only. Ensure compliance with RoHS directives if applicable to the target market. Validate that the UMT3F footprint aligns with the PCB design requirements before finalizing procurement.

Selection Notes

Select this component when a PNP digital transistor with high gain and specific resistor ratios is needed for automotive environments. Compare internal resistor values against circuit requirements to ensure proper biasing. Consider the UMT3F package dimensions for board space constraints. Evaluate thermal performance based on the 200 mW power dissipation limit in the intended operating environment.

Part Context

This part belongs to Rohm's DTA123 series of pre-biased transistors, which combine NPN or PNP transistors with internal resistors. The JUB variant specifically utilizes the UMT3F package. It serves as a legacy option within the portfolio, often replaced by newer packages like UMT3 for new designs while maintaining compatibility for existing systems.

Replacement Considerations

DTA123JU3HZGT106 is a similar specification replacement with a UMT3 package.
