Overview
The PDTC143XQAZ is an NPN Resistor-Equipped Transistor (RET) housed in a DFN1010D-3 (SOT1215) leadless ultra-small plastic package. It features built-in bias resistors with R1 at 4.7 kΩ and R2 at 10 kΩ. The device supports a collector-emitter voltage of 50 V and an output current capability of 100 mA. It operates within a junction temperature range of -55 °C to +150 °C and has a total power dissipation of 280 mW on a single-sided FR4 PCB. The component is AEC-Q101 qualified for automotive applications.
Feature Summary
- Integrated bias resistors simplify circuit design and reduce component count
- Low profile package height of 0.37 mm suitable for space-constrained designs
- Visible and solderable side pads facilitate Automatic Optical Inspection (AOI)
- Qualified to AEC-Q101 standards for automotive reliability
Applications
- Controlling IC inputs
- Digital switching loads
- Cost-saving alternative for BC847/BC857 series in digital applications
Procurement Notes
Verify the specific suffix 'QA' corresponds to the DFN1010D-3 package variant when sourcing. Confirm that the ordering part number includes the correct tape and reel configuration required for automated assembly processes. Ensure compatibility with standard reflow soldering profiles defined for this leadless package type.
Selection Notes
Select this component when a compact NPN transistor with integrated base and pull-down resistors is required. The 4.7 kΩ input resistor and 10 kΩ emitter-base resistor provide specific biasing characteristics distinct from other RET variants like the PDTC143ZQA. Consider the low thermal resistance on multi-layer PCBs for high-density layouts.
Part Context
This device belongs to the Nexperia PDTC143X/123J/143Z/114YQA family of 50 V, 100 mA NPN resistor-equipped transistors. All members share the same DFN1010D-3 package and general electrical structure but differ in internal resistor values. The PDTC143XQA specifically utilizes a 4.7 kΩ R1 and 10 kΩ R2 configuration.
Replacement Considerations
PDTC143XT serves as a functional equivalent in the SOT23 package. For direct pin-compatible replacement in the DFN1010D-3 footprint, verify availability of other family members such as PDTC143ZQA or PDTC123JQA if resistor ratios require adjustment.
