Overview
The DTC143ZCAHZGT116 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It integrates bias resistors with a typical input resistance of 4.7 kOhms and a typical resistor ratio of 10. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 50 V, a continuous collector current of 100 mA, and a power dissipation rating of 350 mW. The device features a minimum DC current gain (hFE) of 80 at 10 mA and 5 V, with a maximum operating frequency of 250 MHz. It is qualified to AEC-Q101 standards for automotive applications.
Feature Summary
- Integrates internal bias resistors to simplify circuit design by eliminating external components.
- Qualified to AEC-Q101 automotive reliability standards for high-temperature operation.
- Optimized for low saturation voltage to enhance switching efficiency.
Applications
- Inverter circuits
- Interface drivers
- General-purpose switching applications
Procurement Notes
Verify the complete part number including the suffix GT116 to ensure correct packaging configuration. Confirm AEC-Q101 qualification requirements if deploying in automotive environments. Cross-reference datasheet specifications against target circuit constraints before procurement.
Selection Notes
Select this component when a single NPN digital transistor with integrated biasing is required in an SOT-23-3 footprint. Ensure the 50 V collector-emitter voltage and 100 mA current ratings exceed the application's peak operational demands. Verify that the 4.7 kOhm input resistance aligns with the driving source capabilities.
Part Context
This part belongs to the DTC143 series of pre-biased transistors from ROHM. It shares the same core transistor structure as variants like DTC143ZCAT116 but differs in packaging and specific automotive-grade qualification. The ZCA designation indicates the specific resistor network configuration within the SST3 package.
Replacement Considerations
DTA143ZCAHZGT116 serves as the PNP counterpart within the same family. For direct substitution, verify polarity requirements and ensure the replacement maintains identical package dimensions and thermal characteristics.
