DDTC143XUA-7-F

Overview

The DDTC143XUA-7-F is a 50V NPN pre-biased transistor in an SOT323 package. It features built-in biasing resistors with nominal values of R1 = 4.7kΩ and R2 = 10kΩ, providing a resistance ratio of approximately 2.13. The device supports a maximum collector current (IC) of 100mA and has a power dissipation rating of 200mW. Key electrical characteristics include a minimum DC current gain (hFE) of 30 at IC=10mA and VCE=5V, a transition frequency (fT) of 250MHz, and a maximum collector-emitter breakdown voltage (VCEO) of 50V.

Feature Summary

Epitaxial planar die construction for reliable performance
Integrated biasing resistors simplify circuit design by eliminating external components
Surface mount SOT323 package optimized for automated assembly

Applications

General-purpose switching applications
Inverter circuits utilizing built-in biasing
Automotive electronics requiring specific change control protocols

Procurement Notes

Verify the part number against official Diodes Incorporated documentation to ensure authenticity. Confirm that the ordering suffix matches the required packaging specifications. Check for compliance with RoHS and REACH directives as specified in the datasheet. Ensure storage conditions adhere to the moisture sensitivity level requirements before soldering.

Selection Notes

Select this component when a compact NPN solution with integrated base and emitter-base resistors is required. The 4.7kΩ input resistor and 10kΩ emitter-base resistor configuration suits specific logic interface needs. Consider the 200mW power dissipation limit and thermal resistance when designing the PCB layout.

Part Context

This component belongs to the DDTC (R1≠R2 Series) UA family from Diodes Incorporated. It is specifically designed for surface mount applications requiring small form factors. The series offers various resistor combinations to accommodate different drive requirements while maintaining a consistent physical footprint and electrical profile.

Replacement Considerations

Direct substitutes within the same series include DDTC143FUA-7-F and DDTC143ZUA-7-F, which share the SOT323 package but feature different resistor values. Verify that alternative part numbers meet the specific R1 and R2 requirements of the original design.
