Overview
The PDTC143EU,115 is an NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia in a SOT323 (SC-70) surface-mount package. It integrates bias resistors R1 and R2, both nominally 4.7 kΩ, with 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 is rated at 200 mW at 25 °C ambient temperature. Operating junction temperature ranges from -65 °C to +150 °C. Pin 1 serves as the input (base), Pin 2 as ground (emitter), and Pin 3 as the output (collector).
Feature Summary
- Integrates built-in bias resistors to simplify circuit design and reduce component count.
- Provides 100 mA output current capability for switching applications.
- Utilizes a compact SOT323 plastic surface-mounted package.
Applications
- Digital applications in industrial segments
- Cost-saving alternative for BC847 series in digital applications
- 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. Ensure the procurement channel sources directly from authorized distributors to guarantee product authenticity and traceability. Confirm RoHS compliance status through the manufacturer's latest declarations before finalizing orders.
Selection Notes
Select this component when a single NPN transistor with integrated base and emitter biasing is required. The 4.7 kΩ resistor values are suitable for standard logic interface applications. Verify that the 50 V collector-emitter voltage rating meets the system requirements. Consider the SOT323 footprint constraints during PCB layout planning.
Part Context
This part belongs to the Nexperia PDTC143E series of NPN resistor-equipped transistors. The PDTA143EU serves as the PNP complement within the same family. These devices are designed to replace discrete resistor-transistor combinations, offering space savings and simplified assembly processes in digital logic circuits.
Replacement Considerations
The PDTA143EU is the documented PNP complement. For direct functional substitution in similar NPN configurations, verify equivalent resistor values and voltage ratings. Cross-reference with other RET families only if pin compatibility and electrical parameters match exactly.
