Overview
The NHDTA143ZT-QR is a PNP Resistor-Equipped Transistor (RET) manufactured by Nexperia, housed in an SOT-23 surface-mount package. It integrates a single PNP bipolar junction transistor with internal biasing resistors to simplify circuit design and reduce component count. Key electrical specifications include a maximum collector-emitter 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 and is available in reel, cut tape, and MouseReel packaging formats.
Feature Summary
- Integrates PNP transistor with built-in biasing resistors for simplified switching applications
- Compact SOT-23 surface-mount package suitable for space-constrained designs
- High thermal stability with extended operating temperature range up to 150 °C
Applications
- General-purpose switching circuits
- Logic level translation interfaces
- Driver stages for low-power loads
Procurement Notes
Verify the specific suffix 'QR' against the official Nexperia datasheet to confirm packaging details and compliance status. Ensure compatibility with automated assembly processes by checking reel specifications. Confirm RoHS and REACH compliance requirements for the target market before finalizing procurement orders.
Selection Notes
Select this component when a PNP switching solution with integrated base resistance is required. The 80 V VCEO rating provides headroom for moderate voltage applications. Compare against the NPN complement PDTC143ZT if complementary logic pairs are needed. Verify that the 100 mA current limit meets the load requirements of the specific application circuit.
Part Context
This part belongs to Nexperia's RET family, which combines transistors with pre-configured resistor networks. The NHDA series specifically denotes PNP configurations. The 'Q' suffix typically indicates automotive qualification standards, while 'ZR' specifies the SOT-23 package and reel quantity. This family replaces discrete transistor-resistor combinations to save board space.
Replacement Considerations
Direct functional substitutes include other PNP RETs in SOT-23 packages with similar voltage and current ratings. Check pinout compatibility carefully as resistor values may vary between manufacturers. No specific alternative part numbers are confirmed in the provided documentation.
