DDTC143TE-7

Overview

The DDTC143TE-7 is an NPN pre-biased transistor from Diodes Incorporated, featuring a built-in biasing resistor (R1) with a nominal value of 4.7kΩ. Housed in a compact SOT523 package, this component utilizes epitaxial planar die construction and is fully RoHS compliant. It supports a collector-emitter voltage of 50V and a maximum collector current of 100mA. The device operates within a temperature range of -55°C to +150°C and includes AEC-Q101 qualification for automotive applications.

Feature Summary

Integrates a single internal biasing resistor (R1) to simplify circuit design
AEC-Q101 qualified and PPAP capable for automotive use
Manufactured in IATF 16949 certified facilities
Totally lead-free, halogen-free, and antimony-free green device

Applications

Automotive electronic systems requiring specific change control
General purpose switching applications
Driver circuits for low-power loads

Procurement Notes

Verify the exact part number suffix against the manufacturer's official ordering information to ensure correct packaging quantity and status. Confirm that the R1 tolerance and electrical characteristics align with the specific application requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN solution with integrated base resistance is required. Ensure the 4.7kΩ internal resistor value matches the drive source impedance. Verify that the SOT523 package dimensions fit the PCB layout constraints and that the thermal performance meets the ambient temperature expectations.

Part Context

This part belongs to the DDTC (R1-ONLY SERIES) E family, which offers various resistor values ranging from 1kΩ to 200kΩ. All members share the same SOT523 package and core electrical specifications, differing primarily in the nominal resistance of the integrated biasing resistor.

Replacement Considerations

Direct substitutes include other DDTC series parts with identical R1 values, such as DDTC143TE-7-F. Cross-brand replacements must match the SOT523 footprint, 50V VCEO rating, and 4.7kΩ input resistance.
