DTC143EU3HZGT106

Overview

The DTC143EU3HZGT106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323 (UMT3) surface-mount package. It integrates biasing resistors with typical values of R1 = 4.7 kΩ and R2 = 4.7 kΩ. The device supports a collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Key electrical parameters include a maximum operating frequency of 250 MHz, a DC current gain (hFE) minimum of 20 at 10 mA/5 V, and power dissipation of 200 mW. It is qualified under AEC-Q101 standards for automotive applications.

Feature Summary

• Integrates built-in biasing resistors to simplify circuit design by eliminating the need for external input resistors.
• Qualified for automotive grade reliability under AEC-Q101 standards.
• Designed for high-speed switching operations with a transition frequency up to 250 MHz.

Applications

• Inverter circuits requiring simplified input stages without external base resistors.
• Automotive electronic systems demanding AEC-Q101 compliant components.
• General-purpose switching applications in consumer electronics.

Procurement Notes

Verify the specific suffix GT106 to confirm the tape-and-reel packaging quantity of 3000 units per reel. Ensure compatibility with SOT-323 footprint requirements during PCB layout. Confirm AEC-Q101 qualification status if the application mandates automotive-grade reliability standards. Cross-reference the manufacturer part number against official ROHM documentation to avoid counterfeit components.

Selection Notes

Select this component when a single NPN digital transistor with equal biasing resistors (R1=R2=4.7kΩ) is required. It is suitable for designs needing 50V breakdown voltage and 100mA current handling in a compact SOT-323 package. Consider complementary PNP types like DTA143EU3HZG for push-pull configurations. Verify thermal constraints given the 200mW power dissipation limit in small outline packages.

Part Context

This part belongs to the DTC143 series of pre-biased transistors from ROHM Semiconductor. The EU3 designation indicates specific internal resistor ratios and characteristics within the series. The GT106 suffix denotes the specific taping configuration and reel size. This series is widely used in portable devices and automotive modules where space-saving and simplified biasing are critical.

Replacement Considerations

The DTC143EUAFRA is listed as a similar level replacement with the same pinout and package but is not recommended for new designs. Verify functional equivalence regarding resistor values and hFE ranges before substitution. Check for any differences in automotive qualification status between original and substitute parts.
