Overview
The PDTA144ET-QR is a single NPN digital transistor manufactured by Nexperia, designed for surface-mount applications in the SOT-23 (TO-236AB) package. It integrates an internal biasing network with a typical input resistor of 47 kOhms and a resistor ratio of 1. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA, with a power dissipation rating of 250 mW. It operates within a temperature range of -65°C to +150°C and holds AEC-Q101 qualification for automotive reliability.
Feature Summary
- Integrated biasing network simplifies circuit design by reducing external component count
- Automotive-grade qualification ensures reliability under stringent environmental conditions
- Compact SOT-23 packaging facilitates high-density board layouts
Applications
- Switching applications in automotive electronic control units
- Level shifting and buffer circuits in data communication interfaces
- General-purpose switching in consumer electronics and industrial equipment
Procurement Notes
Verify the specific suffix 'QR' against the official Nexperia datasheet to confirm reel specifications and tape-and-reel dimensions. Ensure compliance with RoHS and REACH regulations as stated in the product documentation. Confirm that the AEC-Q101 qualification meets the specific requirements of the target application environment before finalizing procurement.
Selection Notes
Select this component when a single NPN digital transistor with a 50 V rating and 47 kOhm base resistor is required. Compare against the PNP counterpart NHDTA144ET-QR if polarity inversion is needed. Verify that the 100 mA current capacity and 250 mW power dissipation are sufficient for the intended load conditions and thermal management strategy.
Part Context
This part belongs to Nexperia's portfolio of resistor-equipped transistors, which combine bipolar junction transistors with integrated biasing resistors. The '-Q' suffix indicates automotive qualification, while 'ET' denotes the SOT-23 package and NPN configuration. It is functionally related to other variants like PDTC144TT but differs in package and specific electrical characteristics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult Nexperia's official replacement guide or distributor databases for cross-reference information.
