Overview
The PDTC144VS,126 is an NPN resistor-equipped transistor manufactured by Nexperia (formerly NXP) in the SOT54 (SC-43A/TO-92) through-hole package. It integrates a bias network consisting of R1 (47 kΩ input) and R2 (10 kΩ), yielding a ratio of 0.21. Key electrical parameters include a collector-emitter voltage of 50 V, DC output current of 100 mA, and total power dissipation of 500 mW at 25 °C. The device features a thermal resistance of 250 K/W, a DC current gain of 40 at 5 mA, and a saturation voltage of 150 mV at 10 mA.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design
- Reduces component count and board space requirements
- Suitable for general-purpose switching and amplification tasks
Applications
- Interface circuits
- Driver circuits
- Inverter configurations
Procurement Notes
Verify the ordering suffix '126' against official Nexperia documentation to confirm the specific packing method, as this code indicates tape and reel packaging with wide pitch for the SOT54 variant. Ensure compatibility with assembly equipment specifications before procurement.
Selection Notes
Select the PDTC144VS,126 when a through-hole mounting solution is required for NPN switching applications. The integrated bias network eliminates external resistors, reducing design complexity. Verify that the 500 mW power dissipation rating meets the thermal constraints of the target application environment.
Part Context
This component belongs to the PDTC144V series of NPN resistor-equipped transistors. The series includes various surface-mount packages such as SC-75, SC-59A, and SC-70. The PDTC144VS specifically utilizes the SOT54 plastic single-ended leaded package, offering a distinct form factor compared to the surface-mount variants within the same product family.
Replacement Considerations
The PNP complement PDTA144VS serves as the complementary device within the same series. Other package variants like PDTC144VE or PDTC144VK offer identical electrical characteristics but differ in physical footprint and mounting style.
