Overview
The PDTC143ET-QR is an NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia USA Inc. It integrates a single NPN transistor with built-in bias resistors R1 and R2, both nominally 4.7 kΩ, within a compact SOT-23 (TO-236AB) surface-mount package. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous output current (IO) of 100 mA. It features a typical transition frequency (fT) of 230 MHz and a total power dissipation (Ptot) of 250 mW at 25 °C ambient temperature. Qualified under AEC-Q101 standards, it operates across a junction temperature range of -65 °C to +150 °C.
Feature Summary
- Integrates NPN transistor with dual bias resistors to simplify circuit design and reduce component count.
- Qualified according to AEC-Q101 for automotive applications.
- Provides cost-saving alternative for discrete digital switching solutions.
Applications
- Digital applications in automotive and industrial segments
- Controlling IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as reel size or tape width. Confirm that the requested variant matches the required AEC-Q101 qualification status if automotive compliance is mandatory for the target application environment.
Selection Notes
Select this component when a small SOT-23 footprint is required for NPN switching with integrated base biasing. Ensure the 4.7 kΩ resistor values align with the driving logic levels and desired saturation characteristics. Verify thermal constraints against the 250 mW dissipation limit and derating curves for the specific PCB copper area.
Part Context
This part belongs to the PDTC143 series of resistor-equipped transistors from Nexperia. The 'ET' designation indicates the SOT-23 plastic package type, while the '-Q' suffix denotes AEC-Q101 automotive qualification. The 'R' suffix typically refers to the reel packaging format used for automated surface-mount assembly processes.
Replacement Considerations
The PDTA143ET is the PNP complement within the same family. For direct NPN replacements, verify equivalent VCEO, IO, and resistor ratios in other RET families, ensuring package compatibility with the existing SOT-23 footprint.
