Overview
The DTC114YCAHZGT116 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It features built-in bias resistors with typical values of 10 kOhms for R1 and 47 kOhms for R2. The device supports a collector continuous current of 100 mA and a maximum operating frequency of 250 MHz. Key electrical ratings include a collector-emitter voltage (VCEO) of 50 V, an emitter-base voltage (VEBO) of 5 V, and power dissipation of 350 mW. It meets AEC-Q101 automotive qualification standards and operates up to +150°C.
Feature Summary
- Integrates thin-film bias resistors to simplify circuit design by eliminating external input components.
- Provides complete isolation between resistors to allow negative input biasing without parasitic effects.
- Automotive-grade reliability certified under AEC-Q101 standards for high-temperature operation.
Applications
- Inverter circuits
- Interface logic drivers
- General-purpose switching applications
Procurement Notes
Verify the specific suffix GT116 against the official datasheet to confirm the reel packaging quantity and tape specifications. Ensure the component matches the required AEC-Q101 automotive grade if used in vehicle electronics. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit parts.
Selection Notes
Select this component when a pre-biased NPN transistor is required for space-constrained designs. The integrated resistor ratio simplifies base drive calculations. Verify that the 50 V collector-emitter voltage rating exceeds the maximum circuit load. Confirm compatibility with the target PCB footprint for the SOT-23-3 package.
Part Context
This part belongs to the DTx series of digital transistors from ROHM Semiconductor. It serves as the NPN counterpart to the PNP DTA114YCAHZG. Both devices share similar packaging and automotive qualifications, offering complementary solutions for push-pull or differential driver configurations in electronic systems.
Replacement Considerations
The DTC114YCAT116 is a verified alternative within the same series. It shares the NPN polarity, SOT-23-3 package, and 10 kOhm base resistance. Verify that the power dissipation rating of 200 mW for the CAT variant is sufficient for the application thermal requirements compared to the 350 mW rating of the HZG variant.
