ADTC144ECAQ-13

Single, Pre-Biased Bipolar Transistors Overview

The ADTC144ECAQ-13 is an NPN pre-biased transistor manufactured by Diodes Incorporated, housed in a surface-mount SOT23 package. It features built-in biasing resistors where R1 equals R2, with a nominal value of 47 kΩ. The device is AEC-Q101 qualified for automotive applications and operates within a supply voltage range up to 50 V. Key electrical parameters include a maximum collector current of 100 mA, a DC current gain (Gl) minimum of 80, and a transition frequency (fT) of 250 MHz. Power dissipation is rated at 310 mW, with an operating temperature range spanning from -55°C to +150°C.

Single, Pre-Biased Bipolar Transistors Feature Summary

• Epitaxial planar die construction with integrated biasing resistors (R1 = R2) simplifies circuit design by eliminating external input resistors.
• Qualified for automotive applications under AEC-Q101 standards, ensuring high reliability and compliance with PPAP requirements.
• Manufactured in IATF 16949 certified facilities using halogen-free and antimony-free green molding compounds.

Single, Pre-Biased Bipolar Transistors Applications

• Automotive interface circuits requiring specific change control protocols.
• Driver applications utilizing the pre-biased configuration for simplified switching.
• Inverter circuits leveraging the internal resistor network for stable operation.

Single, Pre-Biased Bipolar Transistors Procurement Notes

Verify the ordering suffix '-13' corresponds to the 10,000-unit reel packaging format as specified in the manufacturer's documentation. Confirm that the required quantity aligns with this standard carrier size. Ensure compliance with RoHS 2 and RoHS 3 directives if environmental regulations apply to the final assembly. Cross-reference the date code marking 'YM' on the component body against the manufacturing year chart to validate production timing.

Single, Pre-Biased Bipolar Transistors Selection Notes

Select this component when an NPN digital transistor with equal base and emitter biasing resistors is required. The 47 kΩ internal resistance values are suitable for standard logic interfacing. Consider the SOT23 package dimensions for space-constrained PCB layouts. Verify that the 50 V collector-emitter voltage rating meets the system's maximum supply requirements. Ensure the thermal management strategy accommodates the 310 mW power dissipation limit under expected ambient conditions.

Single, Pre-Biased Bipolar Transistors Part Context

This part belongs to the ADTC series of NPN pre-biased transistors from Diodes Incorporated. It shares the same epitaxial planar construction and functional characteristics as other members of the family but differs in packaging and internal resistor configurations. The ADTC144 variant specifically denotes the 47 kΩ resistor ratio. It serves as a complementary counterpart to the PNP DTA series devices.

Single, Pre-Biased Bipolar Transistors Replacement Considerations

Direct substitutes within the same family include the ADTC144ECAQ-7, which offers identical electrical specifications but is packaged in a 3,000-unit reel instead of the 10,000-unit reel associated with the -13 suffix. No alternative manufacturers or cross-brand equivalents are documented in the provided source material.
