DTC123JUBHZGTL

Overview

The DTC123JUBHZGTL is a PNP digital transistor manufactured by Rohm Semiconductor, featuring built-in bias resistors within a UMT3F (SOT-323FL) surface-mount package. It supports a collector current of 100 mA and operates with a supply voltage up to 50 V. The device includes an input resistance (R1) of 2.2 kΩ and an emitter-base resistance (R2) of 47 kΩ. Key electrical parameters include a transition frequency of 250 MHz, maximum power dissipation of 200 mW, and a saturation voltage of 300 mV at specific test conditions. It holds AEC-Q101 automotive qualification.

Feature Summary

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

Applications

• Automotive electronic control units requiring qualified discrete components
• Inverter circuits in consumer electronics
• Switching applications in portable devices

Procurement Notes

Verify the component status as not recommended for new designs before procurement. Confirm that the UMT3F package dimensions match the target PCB footprint. Ensure the AEC-Q101 qualification meets specific automotive project requirements. Check for available replacement models if long-term supply stability is critical for the production timeline.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required for automotive or high-reliability applications. The 2.2 kΩ input resistance suits standard logic interface levels. Consider the 200 mW power dissipation limit for thermal management. Verify compatibility with the UMT3F package size against alternative SOT-323 variants if pinout or height constraints exist.

Part Context

This part belongs to Rohm's DTC123 series of NPN/PNP digital transistors. It serves as the PNP counterpart to the DTC123JUBHZGTL family. The series is designed for general-purpose switching and level shifting. The UMT3F package provides a small form factor suitable for modern compact electronic assemblies.

Replacement Considerations

DTA123JU3HZGT106 is listed as a similar specification replacement with a UMT3 package.
