DTA124XU3HZGT106

Overview

The DTA124XU3HZGT106 is a single PNP bias resistor built-in transistor manufactured by ROHM Semiconductor. It features an integrated base resistor (R1) of 22 kOhms and an emitter-base resistor (R2) of 47 kOhms, with a typical resistance ratio of 2.1. The device supports a collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. Key electrical parameters include a minimum DC current gain (hFE) of 68 at -5 mA and -5 V, a maximum operating frequency of 250 MHz, and a power dissipation rating of 200 mW. It operates within a temperature range up to +150°C and is housed in a SOT-323-3 package.

Feature Summary

• Integrates bias resistors to simplify circuit design by eliminating external components
• Qualified for automotive applications under AEC-Q101 standards
• Optimized for high-speed switching with a transition frequency of 250 MHz

Applications

• Automotive digital logic circuits requiring high reliability
• Interface circuits between microcontrollers and peripheral devices
• Inverter circuits for signal processing

Procurement Notes

Verify the specific suffix GT106 against official ROHM documentation to confirm packaging details and tape-and-reel specifications. Ensure compatibility with SOT-323 footprint requirements during PCB layout. Cross-reference the AEC-Q101 qualification status if the application mandates automotive-grade certification. Confirm that the 22k/47k resistor values align with the target circuit's drive requirements.

Selection Notes

Select this component when a PNP configuration with a 22k input resistance is required. The 47k emitter-base resistor provides specific leakage characteristics distinct from other ratios in the series. Consider the 200mW power dissipation limit for thermal management in dense layouts. Verify that the -50V rating meets the system's voltage headroom needs.

Part Context

This part belongs to the DTA124X series of bias resistor built-in transistors. It shares the same internal topology as variants like DTA124XU3T106 but may differ in packaging or specific qualification grades. The 'EU3' or similar suffixes often denote specific automotive or industrial grade variations within the broader DTC/DTA family.

Replacement Considerations

Direct substitutes include DTA124XU3T106 and DTA124XE3HZGTL, provided the package and resistor values match. Verify pinout compatibility and ensure the alternative meets the same AEC-Q101 requirements if used in automotive contexts.
