Overview
The DTA144ECAHZGT116 is a PNP digital transistor with built-in resistors, manufactured by ROHM Semiconductor. It features a single configuration in an SOT-23 (SST3) package. Key electrical parameters include a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device incorporates biasing resistors R1 and R2, both rated at 47 kOhms. Power dissipation is specified at 200 mW, with a maximum operating temperature of +150°C. It meets AEC-Q101 automotive qualification standards.
Feature Summary
- Integrates biasing resistors to simplify circuit design for inverter applications
- Automotive-grade reliability compliant with AEC-Q101 standards
- Surface-mount construction suitable for compact PCB layouts
Applications
- Inverter circuits
- Interface circuits
- Driver circuits
Procurement Notes
Verify the specific suffix GT116 against official datasheets to confirm reel packaging and tape specifications. Ensure compatibility with existing BOM requirements for automotive grade components. Cross-reference part numbers with authorized distributors to avoid obsolete or non-compliant variants during sourcing.
Selection Notes
Select this component when a PNP digital transistor with equal 47 kOhm biasing resistors is required. Consider the SOT-23 package size constraints and the -50 V voltage rating. Verify thermal management needs against the 200 mW power dissipation limit in the target application environment.
Part Context
This part belongs to ROHM's line of PNP digital transistors designed for automotive use. It complements NPN counterparts like the DTC144 series. The ECAHZG suffix indicates the specific resistor values and package type within the broader DTA144 family.
Replacement Considerations
DTA144EUAFRA is listed as a similar level replacement with the same pinout and package. Verify resistor values and hFE characteristics before substitution.
