Overview
The NHDTA144ET-QR is a PNP Resistor-Equipped Transistor (RET) from Nexperia, housed in an SOT-23 (TO-236AB) surface-mount package. It integrates a PNP bipolar junction transistor with two internal resistors. Key electrical parameters include a collector-emitter maximum voltage (VCEO) of 80 V and an emitter-base voltage (VEBO) of 10 V. The device supports a continuous collector current of 100 mA with a power dissipation rating of 250 mW. It operates within a temperature range of -55°C to +150°C.
Feature Summary
- Integrates a PNP transistor with dual internal biasing resistors to reduce component count.
- Automotive-grade qualification compliant with AEC-Q101 standards for reliability.
- Compact SOT-23 packaging designed for space-constrained surface-mount applications.
Applications
- Automotive logic level shifting and switching circuits
- General-purpose signal switching in embedded systems
- Interface circuits requiring compact pre-biased transistor solutions
Procurement Notes
Verify the specific suffix 'QR' against the manufacturer's official datasheet to confirm reel specifications and tape-and-reel dimensions. Ensure the automotive grade designation aligns with project requirements. Cross-reference the Mouser part number 771-NHDTA144ET-QR for accurate sourcing channels. Confirm RoHS compliance status through the latest product documentation before integration.
Selection Notes
Select this component when a PNP switching solution with integrated biasing is required in a small footprint. The 80 V VCEO rating suits moderate voltage applications. Verify that the 100 mA collector current meets load demands. Consider the SOT-23 thermal characteristics for power dissipation limits. Compare against other RET families if different resistor values or NPN configurations are needed.
Part Context
This part belongs to Nexperia's NHDTA series of PNP Resistor-Equipped Transistors. The series offers various resistor combinations within standard packages like SOT-23. The '-Q' suffix typically denotes automotive qualification, while '-R' indicates reel packaging. This family simplifies circuit design by replacing discrete transistor-resistor networks.
Replacement Considerations
Check for direct substitutes within the NHDTA144ETVL or NHDTA144EVL series for similar electrical characteristics. Verify pinout compatibility with SOT-23/TO-236AB footprints. Ensure replacement parts maintain AEC-Q101 automotive qualification if used in vehicle electronics. Confirm identical resistor values and transistor polarity.
