Overview
The PDTC143ZT-QR is a single NPN resistor-equipped transistor (RET) manufactured by Nexperia. It integrates an NPN bipolar junction transistor with internal biasing resistors in a compact SOT-23 surface-mount package. The device features a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Power dissipation is rated at 250 mW, with an operating temperature range from -65 °C to +150 °C. It holds AEC-Q101 qualification for automotive applications.
Feature Summary
- Integrates NPN transistor with built-in biasing resistors to reduce component count
- AEC-Q101 qualified for automotive reliability standards
- Compact SOT-23 surface-mount package design
Applications
- Automotive electronic circuits requiring space-saving switching solutions
- General-purpose digital switching and logic level translation
- Driver circuits for low-power loads in constrained PCB areas
Procurement Notes
Verify the specific suffix 'QR' against the official Nexperia datasheet to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the order matches the exact part number including the '-Q' designation for automotive grade compliance. Cross-reference the manufacturer's 12NC code for accurate inventory tracking.
Selection Notes
Select this component when a single NPN switch with integrated base and emitter resistors is required. Compare the 50 V rating against circuit voltage peaks. Verify that the SOT-23 thermal performance meets system dissipation requirements. Confirm AEC-Q101 qualification is necessary for the target application environment.
Part Context
This part belongs to the Nexperia PDTC143 series of pre-biased transistors. It serves as the NPN complement to the PNP PDTA143ZT variant. The series provides a consolidated solution for driving applications, replacing discrete transistor-resistor networks with a single surface-mount component.
Replacement Considerations
Publicly confirmed substitutes include the PDTC143ZT without the automotive suffix or other Nexperia RETs with matching 50 V ratings and SOT-23 packages. Verify pinout compatibility before substitution.
