Overview
The PDTC144TT,215 is an NPN resistor-equipped transistor manufactured by Nexperia in a SOT-23 (TO-236AB) surface-mounted package. It integrates a single bias resistor with a typical 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 500 K/W under standard mounting conditions. The component operates within an ambient temperature range of -65 °C to +150 °C.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design
- Reduces overall component count and pick-and-place costs
Applications
- General purpose switching and amplification
- Inverter and interface circuits
- Circuit driver applications
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm manufacturing origin and compliance status. Confirm that the SOT-23 package variant matches the required footprint for the target PCB layout. Ensure the open R2 configuration aligns with the intended biasing requirements before finalizing procurement orders.
Selection Notes
Select this component when a single external base resistor is sufficient for the application logic. The open internal connection for the second resistor distinguishes it from dual-resistor variants. Verify that the 47 kΩ input impedance meets the drive source requirements for the specific switching frequency and load conditions.
Part Context
This part belongs to the PDTC144T series of NPN resistor-equipped transistors. It serves as the electrical complement to the PDTA144TT PNP counterpart. The series provides standardized biasing solutions for discrete semiconductor applications requiring simplified integration of switching elements.
Replacement Considerations
The PDTA144TT is the documented PNP complement within the same product family. Other package versions such as PDTC144TU or PDTC144TM offer alternative form factors but maintain identical electrical characteristics.
