Overview
The DTC143ZU3HZGT106 is a single NPN digital transistor manufactured by ROHM Semiconductor, designed for surface-mount applications in the UMT3 (SOT-323) package. It integrates biasing resistors to simplify circuit design without external components. Key electrical parameters include a collector-emitter voltage of 50 V, continuous collector current of 100 mA, and power dissipation of 200 mW. The device features an input resistance of 4.7 kOhms and an emitter-base resistance of 47 kOhms. It achieves a minimum DC current gain of 80 at 10 mA and 5 V, with a maximum operating frequency of 250 MHz. The component is qualified under AEC-Q101 standards for automotive reliability.
Feature Summary
- Integrates built-in biasing resistors to enable inverter circuit configuration without external input resistors.
- Complies with AEC-Q101 standards for high-reliability automotive grade applications.
- Provides simplified on/off control operation through pre-biased internal structure.
Applications
- Automotive electronic circuits requiring AEC-Q101 compliance
- Inverter circuits utilizing built-in biasing resistors
- General-purpose switching applications in consumer electronics
Procurement Notes
Verify the specific suffix GT106 to confirm the tape and reel packaging format and quantity. Ensure the ordering part number matches the required automotive qualification status. Cross-reference the manufacturer datasheet for exact mechanical dimensions and marking codes before finalizing procurement specifications.
Selection Notes
Select this component when a single NPN digital transistor with integrated biasing is required in a compact SOT-323 package. Consider the 4.7 kOhm input resistance and 47 kOhm emitter-base resistance values for bias network compatibility. Verify that the 50 V collector-emitter voltage and 100 mA current ratings meet the target application requirements.
Part Context
This part belongs to the DTC143 series of digital transistors from ROHM Semiconductor. The series includes complementary PNP types such as DTA143 variants. The U3HZG suffix indicates the specific resistor ratio and packaging configuration within the broader DTC143 family designed for space-constrained designs.
Replacement Considerations
DTC143ZUAFRA is listed as a similar level replacement with the same pinout and package, though it is not recommended for new designs. Other manufacturers offer generic DTC143ZUA equivalents, but verification of electrical parameters and AEC-Q101 compliance is necessary.
