DTA124ECAHZGT116

Overview

The DTA124ECAHZGT116 is a single PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors within an SOT-23-3 (SST3) surface-mount package. It operates with a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes a typical input resistance (R1) of 22 kOhms and an emitter-base resistance (R2) of 22 kOhms, maintaining a resistor ratio of 1. Key electrical characteristics include a minimum DC current gain (hFE) of 20 at -20 mA and -5 V, a maximum operating frequency of 250 MHz, and a power dissipation rating of 350 mW. It is qualified under AEC-Q101 standards for automotive applications.

Feature Summary

• Integrates bias resistors to simplify circuit design by eliminating external components
• Automotive-grade reliability certified under AEC-Q101 standards
• Compact SOT-23-3 package suitable for space-constrained surface-mount applications

Applications

• Inverter circuits
• Interface drivers
• Automotive electronic systems

Procurement Notes

Verify the specific suffix GT116 against official ROHM documentation to confirm reel packaging and tape specifications. Ensure compatibility with AEC-Q101 requirements if used in automotive designs. Cross-reference the SST3 package dimensions with PCB footprint guidelines. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing procurement orders.

Selection Notes

Select this component when a PNP digital transistor with equal bias resistor values (R1=R2=22k) is required. The 250 MHz transition frequency supports high-speed switching applications. Verify that the -50V collector-emitter voltage rating meets the system's supply constraints. Consider the 350 mW power dissipation limit for thermal management in dense layouts.

Part Context

This part belongs to the DTx series of digital transistors from ROHM Semiconductor. The 'DTA' prefix indicates a PNP polarity configuration. The '124' designation typically corresponds to the 22 kOhm resistor value combination. The 'CAH' suffix often denotes specific automotive qualification or package variations within the broader DTC/DTA family.

Replacement Considerations

The DTA124EU3HZGT106 is listed as a recommended replacement with similar specifications but in a UMT3 package. Verify pinout compatibility and physical footprint differences between SOT-23-3 and UMT3/SOT-323 variants before substitution.
