Overview
The PDTC143ZQAZ is an NPN Resistor-Equipped Transistor (RET) from Nexperia, housed in a leadless DFN1010D-3 (SOT1215) surface-mount package. It features built-in bias resistors with R1 at 4.7 kΩ and R2 at 47 kΩ. The device supports a collector-emitter voltage of 50 V and a continuous output current of 100 mA. It operates within an ambient temperature range of -55°C to +150°C and includes AEC-Q101 qualification for automotive reliability.
Feature Summary
- Integrated bias resistors simplify circuit design and reduce component count
- AEC-Q101 qualified for automotive application suitability
- Ultra-thin package height of 0.37 mm facilitates compact layouts
- Visible and solderable side pads enable Automatic Optical Inspection
Applications
- Digital applications in automotive and industrial segments
- Controlling IC inputs
- Switching loads
- Cost-saving alternative for BC847/BC857 series in digital applications
Procurement Notes
Verify the specific ordering suffix 'QAZ' against the manufacturer's current documentation to confirm packaging details such as reel or cut tape configuration. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability for this AEC-Q101 qualified component.
Selection Notes
Select the PDTC143ZQAZ when a low-profile NPN RET with a 4.7 kΩ input resistor and 47 kΩ pull-down resistor is required. This part serves as a direct replacement for discrete resistor-transistor networks in space-constrained designs. Confirm that the 50 V rating and 100 mA current capability align with the target load requirements.
Part Context
This component belongs to the PDTC143X/123J/143Z/114YQA series of 50 V, 100 mA NPN resistor-equipped transistors. The 'Z' designation specifically indicates the 4.7 kΩ / 47 kΩ resistor ratio combination. The QAZ suffix denotes the specific packaging variant within the DFN1010D-3 form factor.
Replacement Considerations
The PNP complement is PDTA143ZQA. Other series members include PDTC143XQA (4.7 kΩ/10 kΩ), PDTC123JQA (2.2 kΩ/47 kΩ), and PDTC114YQA (10 kΩ/47 kΩ). Verify pinout compatibility if substituting with other RET families.
