Overview
The PDTC144VK,115 is an NPN resistor-equipped transistor from the PDTC144V series, housed in a SC-59A (SOT346) plastic surface-mounted package. It integrates built-in bias resistors R1 and R2 with typical values of 47 kΩ and 10 kΩ respectively, yielding a ratio of 0.21. The device supports a collector-emitter voltage of 50 V and a DC output current of 100 mA. Key electrical characteristics include a minimum DC current gain of 40 at 5 mA and a maximum collector-emitter saturation voltage of 150 mV at 10 mA. Total power dissipation is rated at 250 mW at 25 °C ambient temperature.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design and reduce component count.
- Reduces board space requirements and pick-and-place costs for interface applications.
- Suitable for general-purpose switching and amplification tasks.
Applications
- Interface circuits
- Driver circuits
- Inverter configurations
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and marking codes. Confirm that the SC-59A package variant aligns with the intended PCB footprint and assembly process requirements before finalizing procurement orders.
Selection Notes
Select this component when a compact NPN solution with integrated biasing is required for space-constrained designs. Ensure the 50 V collector-emitter voltage rating meets the system's maximum operating conditions. Verify that the 100 mA continuous current capability satisfies the load requirements for the specific switching or amplification application.
Part Context
This part belongs to the PDTC144V series of NPN resistor-equipped transistors manufactured by Nexperia. The series includes various package options such as SOT416, SOT883, and SOT23. The PDTC144VK specifically utilizes the SC-59A package, offering a distinct pinout configuration compared to other variants in the family.
Replacement Considerations
The PDTA144VK serves as the PNP complement within the same series. Designers requiring a complementary polarity device should verify the specific package compatibility and electrical parameter symmetry between the NPN and PNP counterparts.
