Overview
The ADTA143ECAQ-13 is a PNP pre-biased transistor manufactured by Diodes Incorporated, housed in an SOT23 package. It features built-in biasing resistors with nominal values of R1 = R2 = 4.7 kΩ. The device is AEC-Q101 qualified and suitable for automotive applications. Key electrical parameters include a maximum supply voltage (VCC) of -50 V, a maximum output current (IC) of -100 mA, and a power dissipation (PD) of 310 mW at +25°C. The DC current gain (Gl) has a minimum value of 20 at VO = -5V and IO = -10mA. The operating temperature range spans from -55°C to +150°C.
Feature Summary
- Epitaxial planar die construction with integrated biasing resistors where R1 equals R2.
- Qualified for automotive applications under AEC-Q101 standards with PPAP capability.
- Manufactured in IATF 16949 certified facilities using halogen-free green molding compound.
Applications
- Automotive electronic circuits requiring specific change control protocols.
- General-purpose switching applications utilizing pre-biased PNP configuration.
- Digital logic interface circuits replacing discrete resistor networks.
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 component meets RoHS 3 compliance requirements and ensure the sourcing channel is authorized to guarantee product authenticity and traceability for automotive-grade parts.
Selection Notes
Select this component when a PNP digital transistor with equal internal biasing resistors is required. Ensure the application voltage does not exceed the -50 V supply limit and the current remains within the -100 mA continuous rating. Consider the thermal resistance of 403 °C/W for heat dissipation calculations on minimum copper FR-4 boards.
Part Context
This part belongs to the ADTA143 series of pre-biased transistors from Diodes Incorporated. The 'ADTA' prefix indicates an automotive-grade qualification, while '143' specifies the PNP type with 4.7kΩ/4.7kΩ resistors. The 'ECAQ' suffix denotes the SOT23 package and lead-free composition, distinguishing it from standard commercial variants.
Replacement Considerations
The datasheet lists ADTA143ECAQ-7 as a compatible variant with identical electrical characteristics but packaged in 3,000-unit reels instead of 10,000-unit reels. No other cross-model replacements are documented in the provided source material.
