Overview
The PDTC143EU is an NPN Resistor-Equipped Transistor (RET) housed in a SOT323 (SC-70) surface-mount package. It integrates bias resistors to simplify circuit design and reduce component count. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, an output current (IO) of 100 mA, and a typical input bias resistor (R1) of 4.7 kΩ with a ratio (R2/R1) of 1. The device operates within a temperature range of -65 °C to +150 °C.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design and reduce pick-and-place costs.
- Provides 100 mA output current capability for switching loads.
- Offers a cost-saving alternative to discrete transistor series in digital applications.
Applications
- Digital applications in industrial segments
- Controlling IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details such as reel or cut tape configuration. Confirm that the procurement channel sources directly from authorized distributors to ensure product authenticity and traceability. Check for any recent revision history updates that may affect marking codes or test conditions before finalizing orders.
Selection Notes
Select this component when a compact NPN solution with integrated biasing is required for space-constrained designs. Ensure the application voltage does not exceed the 50 V collector-emitter rating. Verify thermal management requirements against the 200 mW power dissipation limit at 25 °C ambient temperature. Consider the PNP complement PDTA143EU if complementary logic is needed.
Part Context
This part belongs to the Nexperia Resistor-Equipped Transistor (RET) family, designed to replace multiple discrete components. It serves as a direct replacement for standard BC847 series transistors in digital switching roles. The SOT323 package provides a small footprint suitable for high-density PCB layouts.
Replacement Considerations
The PDTA143EU is the documented PNP complement. For automotive-grade equivalents, consult Nexperia products qualified to AEC-Q101 standards, as this specific part is designated as non-automotive.
