Overview
The DTA124XCAHZGT116 is a single PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates within a collector-emitter voltage of -50V and supports a continuous collector current of -100mA. The device incorporates a typical input resistance of 22 kOhms with a resistor ratio of 2.1. Key electrical specifications include a minimum DC current gain (hFE) of 68 at -5mA and -5V, a maximum operating frequency of 250MHz, and a power dissipation rating of 350mW. It is housed in an SOT-23-3 surface-mount package and complies with AEC-Q101 automotive standards.
Feature Summary
- Integrates bias resistors to eliminate external components for inverter circuits
- Automotive-grade reliability compliant with AEC-Q101 qualification standards
- High-speed switching capability suitable for high-frequency applications
Applications
- Inverter circuits
- Interface drivers
- Automotive electronic systems
Procurement Notes
Verify the specific ordering suffix GT116 against official ROHM documentation to confirm reel packaging and tape specifications. Ensure compatibility with SOT-23-3 footprint requirements during PCB layout. Confirm AEC-Q101 certification status if automotive grade validation is required for the target application environment.
Selection Notes
Select this component when a PNP configuration with integrated biasing is required for space-constrained designs. The 22kOhm input resistance offers a standard drive interface. Consider the 350mW power dissipation limit relative to ambient temperature derating curves. Verify that the -50V voltage rating exceeds the maximum circuit supply voltage under all operating conditions.
Part Context
This part belongs to the DTx series of digital transistors from ROHM Semiconductor. It is specifically designated as an automotive-grade component, distinguishing it from general-purpose variants through rigorous qualification testing. The model represents a pre-biased transistor solution designed to replace discrete resistor-transistor combinations in modern electronics.
Replacement Considerations
DTA124XCAT116 shares identical electrical parameters and SOT-23-3 packaging but lacks the explicit automotive designation found in the HZG variant. Designers should verify if AEC-Q101 compliance is mandatory before substituting.
