DTA123JE3HZGTL

Overview

The DTA123JE3HZGTL is a PNP digital transistor from Rohm Semiconductor, classified as an automotive-grade component certified under AEC-Q101 standards. It integrates biasing resistors within a compact SOT-416 (EMT3) surface-mount package. Key electrical specifications include a maximum collector current of -0.1 A and a supply voltage range up to -50 V. The device features typical input resistance values of 1 kΩ or 2.2 kΩ for R1, paired with emitter-base resistances of 1 kΩ or 47 kΩ for R2. It operates with a power dissipation capacity of 0.15 W and maintains a minimum DC current gain (hFE) of 80 at specified test conditions.

Feature Summary

• Integrates built-in biasing resistors to simplify circuit design and reduce component count.
• Automotive-grade reliability compliant with AEC-Q101 qualification standards.
• Compact SOT-416 surface-mount package optimized for space-constrained applications.

Applications

• Automotive electronic control units requiring high-reliability switching.
• General-purpose digital logic interface circuits.
• Level shifting between different voltage domains in embedded systems.

Procurement Notes

Verify the specific resistor ratio configuration (R1/R2 values) required for the application, as the base model supports multiple variants. Confirm that the SOT-416 footprint matches the PCB layout constraints. Ensure the supplier provides documentation confirming AEC-Q101 certification status for automotive deployment compliance.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is needed for automotive environments. Compare the internal resistor values against the driving source impedance to ensure proper saturation. Verify that the 0.15 W power dissipation rating accommodates the thermal requirements of the target enclosure without additional heatsinking.

Part Context

This part belongs to the DTA123 series of pre-biased transistors manufactured by Rohm Semiconductor. The series offers various resistor combinations and packaging options to suit different current and voltage requirements while maintaining a standardized pinout for easy substitution across designs.

Replacement Considerations

Direct substitutes may include other AEC-Q101 qualified PNP digital transistors in SOT-416 packages with matching R1 and R2 values. Verify pin compatibility and thermal characteristics before swapping. Alternative packages like SOT-323 require re-evaluation of the PCB layout.
