Overview
The PDTC143XM,315 is an NPN Resistor-Equipped Transistor (RET) from Nexperia, housed in the SOT883 (SC-101) leadless ultra-small plastic package. It integrates a single NPN transistor with built-in bias resistors: R1 (input/base) is typically 4.7 kΩ and R2 (base/emitter) creates a typical ratio of 2.1 relative to R1. The device supports a collector-emitter voltage (VCEO) of 50 V and a continuous output current (IO) of 100 mA. Total power dissipation is rated at 250 mW at 25 °C ambient temperature. The junction-to-ambient thermal resistance is typically 500 K/W. Operating temperatures range from -65 °C to +150 °C.
Feature Summary
- Integrates NPN transistor with fixed internal bias resistors to reduce component count and simplify circuit design.
- Qualified to AEC-Q101 standards for automotive applications.
- Utilizes a compact SOT883 leadless package for space-constrained surface-mount designs.
Applications
- Digital switching loads
- Control of IC inputs
- Automotive digital applications
- Industrial digital applications
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details and manufacturing origin. Ensure compatibility with reflow soldering profiles as wave soldering is not recommended for this component type. Cross-reference the 12NC code for accurate supply chain tracking.
Selection Notes
Select this component when a compact NPN switching solution with integrated base biasing is required. The SOT883 package offers a smaller footprint compared to standard SOT23 packages. Verify that the 50 V collector-emitter voltage and 100 mA current ratings meet the specific load requirements of the target application circuit.
Part Context
This part belongs to the PDTC143X series of NPN resistor-equipped transistors. Other members include PDTC143XE (SOT416), PDTC143XT (SOT23), and PDTC143XU (SOT323). The PNP complement for this family is the PDTA143XM. All variants share identical electrical characteristics but differ in physical package dimensions and pin configurations.
Replacement Considerations
Direct functional substitutes within the same series include PDTC143XT (SOT23) and PDPC143XU (SOT323), provided the PCB layout accommodates the different package footprints. For leadless SMD replacements, verify mechanical fit for the SOT883 package specifically.
