Overview
The PDTC143EU-Q is an NPN Resistor-Equipped Transistor (RET) housed in a SOT323 (SC-70) surface-mount package. It features built-in bias resistors with R1 at 4.7 kΩ and R2 at 4.7 kΩ, yielding a typical ratio of 1. The device supports a collector-emitter voltage (VCEO) of 50 V and a continuous output current (IO) of 100 mA. Total power dissipation reaches 200 mW at 25 °C ambient temperature. Junction temperature ranges from -65 °C to +150 °C. The component is qualified according to AEC-Q101 standards for automotive applications.
Feature Summary
- AEC-Q101 qualified for automotive reliability
- Built-in bias resistors simplify circuit design
- Reduces component count and pick-and-place costs
Applications
- Digital applications in automotive segments
- Controlling IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as reel or cut tape specifications. Confirm RoHS compliance status through the latest product data sheet before finalizing procurement orders. Ensure the requested quantity aligns with standard factory packaging configurations to avoid handling discrepancies during assembly.
Selection Notes
Select this component when a compact NPN switching solution with integrated base biasing is required. The SOT323 package offers space efficiency for dense PCB layouts. Verify that the 50 V collector-emitter voltage rating meets the maximum operating voltage requirements of the target application circuit. Consider the thermal resistance characteristics if high-power dissipation conditions are expected.
Part Context
This part belongs to Nexperia's resistor-equipped transistor family designed to replace discrete resistor-transistor networks. The 'Q' designation indicates qualification for automotive environments under AEC-Q101 standards. It serves as a cost-effective alternative to traditional discrete components in digital logic and signal processing circuits.
Replacement Considerations
The PDTA143EU is the PNP complement within the same series. For direct pin-compatible replacements, verify equivalent electrical parameters including VCEO, IO, and internal resistor values in competitor datasheets.
