Overview
The DTC124EU3HZGT106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323 (UMT3) surface-mount package. It integrates internal biasing resistors with a typical base resistance of 22 kOhms and an emitter-base resistance of 22 kOhms. The device supports a supply voltage of 50 V and a continuous collector current of 100 mA, with a maximum power dissipation of 200 mW. It features a transition frequency of 250 MHz and meets AEC-Q101 automotive qualification standards.
Feature Summary
- Integrates built-in biasing resistors to simplify circuit design by eliminating external components.
- Automotive-grade reliability compliant with AEC-Q101 qualification standards.
- Compact SOT-323 surface-mount packaging suitable for space-constrained applications.
Applications
- Automotive electronic circuits requiring pre-biased switching elements.
- General-purpose digital logic interface and level shifting.
- Inverter circuits and buffer stages in consumer electronics.
Procurement Notes
Verify the specific ordering suffix GT106 to confirm the tape-and-reel packaging quantity of 3000 units. Ensure compatibility with the UMT3/SOT-323 footprint during PCB layout. Confirm that the AEC-Q101 qualification aligns with target automotive or industrial reliability requirements before finalizing procurement.
Selection Notes
Select this component when a single NPN digital transistor with 22 kOhm input resistance is required. Compare against similar models like DTC124XU3T106 if different resistor ratios are needed. Verify that the 50V collector-emitter voltage and 100mA current ratings exceed the application's peak operating conditions.
Part Context
This part belongs to the ROHM DTC124 series of pre-biased transistors. It serves as a direct replacement for older variants such as the DTC124EUAFRA, which is no longer recommended for new designs. The EU3HZG suffix denotes the specific resistor configuration and automotive-grade construction within the broader DTC124 family.
Replacement Considerations
The DTC124EU3HZGT106 is listed as a recommended replacement for the discontinued DTC124EUAFRA. Both parts share identical pinouts, packages, and electrical characteristics, ensuring drop-in compatibility without circuit redesign.
