DTC115EU3HZGT106

Overview

The DTC115EU3HZGT106 is a single NPN digital transistor manufactured by ROHM Semiconductor. It integrates bias resistors within an SOT-323-3 surface-mount package to simplify circuit design. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device features a typical input resistance of 47 kOhms with a resistor ratio of 1. It operates up to a maximum frequency of 250 MHz, with a minimum DC current gain (hfe) of 68 at 5 mA and 5 V. Power dissipation is rated at 200 mW, and the maximum operating temperature reaches +150°C. The component holds AEC-Q101 qualification for automotive applications.

Feature Summary

• Integrates internal bias resistors to eliminate external components for inverter circuits
• Qualified under AEC-Q101 standards for automotive reliability requirements
• Provides high-speed switching capability suitable for frequencies up to 250 MHz

Applications

• Automotive electronic control units requiring qualified discrete components
• General-purpose inverter circuits in consumer electronics
• Switching applications in portable devices and industrial equipment

Procurement Notes

Verify the specific suffix HZG confirms AEC-Q101 automotive qualification when sourcing. Confirm the 47 kOhm input resistance matches the target circuit design, as this differs from standard 100 kOhm variants. Ensure the SOT-323-3 footprint aligns with the PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this part when automotive qualification is mandatory for NPN digital transistor applications. The 47 kOhm input resistance offers different drive characteristics compared to the 100 kOhm DTC115EU3 variant. Consider the 200 mW power dissipation limit and 50 V voltage rating against the specific load conditions of the target application circuit.

Part Context

This component belongs to the DTC115 series of ROHM's built-in bias resistor transistors. The EU3 designation indicates the SOT-323 package type, while the HZG suffix specifically denotes AEC-Q101 compliance. It serves as a specialized automotive-grade alternative to standard commercial digital transistors like the DTC115EU3.

Replacement Considerations

• DTC115EU3T106: Commercial grade equivalent without automotive qualification
• DTA115TUAT106: PNP polarity counterpart for complementary circuits
