Overview
The PDTC123JU/ZLX is an NPN resistor-equipped transistor (RET) manufactured by NXP Semiconductors. It integrates a base resistor of 2.2 kΩ and an emitter-base resistor of 47 kΩ within a single component. The device is housed in the SOT323 (SC-70) surface-mounted plastic package, designed for compact circuit layouts. It supports a maximum collector current of 100 mA and features high breakdown voltage characteristics suitable for digital switching applications.
Feature Summary
- Integrates biasing resistors to simplify circuit design and reduce component count
- High breakdown voltage capability ensures reliable operation in demanding environments
- Compact SOT323 package minimizes PCB footprint and assembly costs
Applications
- Digital logic interface circuits
- Switching loads in consumer electronics
- Controlling IC inputs in embedded systems
Procurement Notes
Verify the specific suffix /ZLX against official NXP documentation to confirm tape-and-reel packaging specifications and lot traceability requirements. Ensure compatibility with standard SMD pick-and-place equipment given the SC-70 form factor. Cross-reference ordering codes with authorized distributors to validate authenticity and supply chain integrity prior to procurement.
Selection Notes
Select this component when space constraints require integrated biasing solutions. Compare internal resistance values against circuit requirements to ensure proper base drive and leakage performance. Verify thermal dissipation capabilities within the SOT323 package for the intended operating temperature range and load conditions.
Part Context
This part belongs to the PDTC series of NPN resistor-equipped transistors from NXP. It serves as a direct replacement for discrete resistor networks in switching applications. The series offers various resistance combinations and complementary PNP options, providing flexibility for general-purpose digital signal processing and level shifting tasks in modern electronic designs.
Replacement Considerations
The Nexperia NHDTC123JU is a confirmed functional substitute with identical electrical parameters and pinout configuration. Both devices utilize the SOT323 package and share the same 2.2 kΩ/47 kΩ resistor ratio. Verify mechanical tolerances and marking codes during substitution to ensure seamless integration.
