ADTC143TUAQ-13

Single, Pre-Biased Bipolar Transistors Overview

The ADTC143TUAQ-13 is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features built-in biasing resistors and operates within a collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device has a power dissipation rating of 330 mW and a DC current transfer ratio (hFE) ranging from 100 to 600 at IC = 1mA, VCE = 5V. It is housed in an SOT-323 package with a typical input resistor (R1) of 4.7 kΩ. Qualified to AEC-Q101 standards, it supports an operating temperature range from -55°C to +150°C.

Single, Pre-Biased Bipolar Transistors Procurement Notes

Verify the specific ordering suffix '-13' corresponds to the 10,000 units per reel packaging configuration as documented in the manufacturer's ordering information. Confirm that the component meets the required automotive qualification standards if intended for such applications. Ensure compatibility with automated assembly processes given the surface mount package type.

Single, Pre-Biased Bipolar Transistors Selection Notes

Select this component when an NPN pre-biased transistor with a 50 V collector-emitter voltage and 100 mA current capability is required. Consider the SOT-323 package size for space-constrained designs. Verify that the built-in 4.7 kΩ input resistor aligns with the drive requirements of the application circuit. Check thermal derating curves for operation above ambient temperatures.

Single, Pre-Biased Bipolar Transistors Part Context

This part belongs to the ADTC143 series of NPN pre-biased transistors from Diodes Incorporated. The 'TUAQ' designation indicates the SOT-323 package and automotive qualification status. The '-13' suffix specifies the tape and reel quantity of 10,000 units. It is distinct from other variants like the ADTC143ZUAQ which may have different resistor values or packages.

Single, Pre-Biased Bipolar Transistors Replacement Considerations

Direct replacements must match the NPN polarity, 50 V VCEO, 100 mA IC, and SOT-323 package. Verify equivalent hFE ranges and built-in resistor values. Automotive applications require components also qualified to AEC-Q101.
