Overview
The PDTC144TU,115 is an NPN resistor-equipped transistor manufactured by Nexperia in the SOT323 (SC-70) surface-mount package. It integrates a single bias resistor with a nominal value of 47 kΩ, while the second resistor position remains open. The device supports a maximum collector-emitter voltage of 50 V and a continuous DC output current of 100 mA. Thermal resistance from junction to ambient is specified at 625 K/W under standard mounting conditions. Operating temperatures range from -65 °C to +150 °C.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design and reduce component count.
- Reduces pick and place costs associated with discrete resistor assembly.
Applications
- General purpose switching and amplification
- Inverter and interface circuits
- Circuit driver
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm manufacturing origin and compliance status. Confirm RoHS and REACH alignment with project requirements before procurement. Ensure the selected distributor provides traceable supply chain data for quality assurance purposes.
Selection Notes
Select this component when a compact NPN solution with integrated base biasing is required. The SOT323 package offers space efficiency for high-density layouts. Verify that the 47 kΩ internal resistor value aligns with the target drive current and logic level requirements of the application circuit.
Part Context
This part belongs to the PDTC144T series of NPN resistor-equipped transistors. The series includes variants with different packages such as SOT23 and SOT883. All members share the same electrical characteristics but differ in physical footprint and thermal dissipation capabilities based on their respective package standards.
Replacement Considerations
Direct substitutes include other PDTC144T series members like PDTC144TT or PDTA144TU for PNP complementarity. Cross-brand equivalents must match the 50V rating, 100mA current limit, and 47kΩ input resistance within the SC-70 package form factor.
FAQ
What is the configuration of the internal resistors?
The PDTC144TU features one built-in bias resistor (R1) of 47 kΩ. The second resistor position (R2) is left open.
What is the maximum power dissipation for the SOT323 package?
The total power dissipation (Ptot) for the SOT323 package is limited to 200 mW at an ambient temperature of 25 °C.
Is this component suitable for through-hole mounting?
No, the PDTC144TU is designed specifically for surface-mounted device (SMD) installation using the SOT323 plastic package.
