Overview
The PDTC144EQB-Q is a 50 V, 100 mA NPN Resistor-Equipped Transistor (RET) from Nexperia. It integrates bias resistors R1 (47 kΩ nominal) and R2 (open) into an ultra-small DFN1110D-3 (SOT8015) leadless SMD plastic package with side-wettable flanks. The device features a collector-emitter voltage of 50 V, output current capability of 100 mA, and a minimum DC current gain (hFE) of 80 at IC = 5 mA. It operates within a junction temperature range up to 150 °C and is qualified according to AEC-Q101 for automotive applications.
Feature Summary
- Built-in bias resistors simplify circuit design and reduce component count
- Ultra-small leadless package with side-wettable flanks suitable for Automatic Optical Inspection
- Qualified according to AEC-Q101 for use in automotive applications
Applications
- Digital applications
- Controlling IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct packaging and reel specifications. Confirm that the DFN1110D-3 footprint matches the target PCB design requirements. Check for any recent product status changes or obsolescence notices directly from Nexperia before finalizing procurement plans.
Selection Notes
Select this component when space constraints require an ultra-thin profile with a maximum height of 0.5 mm. Choose the PDTC144EQB-Q variant specifically for circuits requiring a 47 kΩ input resistor configuration. Ensure the application environment remains within the specified -55 °C to 150 °C ambient temperature range for reliable operation.
Part Context
This part belongs to the PDTC143/114/124/144EQB-Q series, which shares the same DFN1110D-3 package and electrical characteristics except for the internal bias resistor values. The series provides options for different resistance ratios while maintaining consistent physical dimensions and thermal performance profiles across all variants.
Replacement Considerations
PDTC144TU-QX is a digital transistor alternative but utilizes a SOT323 package rather than the DFN1110D-3 form factor. Verify pinout compatibility and mechanical fit before substitution, as the package differences may require PCB layout modifications.
