Nexperia PDTC143ZT NPN Resistor Equipped Transistor SOT-23

The Nexperia PDTC143ZT is a 4.7 kΩ to 47 kΩ NPN Resistor Equipped Transistor (RET) housed in a compact surface-mount SOT-23 package. This device integrates bias resistors, which helps to reduce component count, simplify circuit design, and lower assembly costs through reduced pick and place operations. It is AEC-Q101 qualified, making it suitable for demanding automotive and industrial environments.

The transistor features a collector-emitter voltage maximum of 50V and a continuous collector current of 100mA, with a power dissipation of 250mW. It includes a base input resistor (R1) of 4.7 kΩ and a base-emitter resistor (R2) of 47 kΩ, ensuring stable operation and consistent performance. The DC current gain (hFE) is a minimum of 100, providing reliable amplification. Its 3-pin SOT-23 design is ideal for space-constrained applications, and the PNP complement (PDTA143ZT) is available for complementary circuit designs.

With its small footprint and robust build, the PDTC143ZT simplifies prototyping and production, making it a versatile choice for power management and general switching applications.
