Overview
The PDTC144TM,315 is an NPN resistor-equipped transistor from the PDTC144T series manufactured by Nexperia. It integrates a single internal bias resistor (R1) of 47 kΩ with R2 left open. The device is housed in the SOT883 leadless ultra-small plastic package, featuring dimensions of 1.0 × 0.6 × 0.5 mm. Key electrical limits include a collector-emitter voltage (VCEO) of -50 V and a DC output current (IO) of -100 mA. Thermal characteristics specify a total power dissipation of 250 mW at 25 °C ambient temperature with a thermal resistance from junction to ambient of 500 K/W.
Feature Summary
- Integrates a built-in 47 kΩ base bias resistor to simplify circuit design
- Reduces component count by eliminating external biasing resistors
- Utilizes a compact SOT883 leadless package for space-constrained applications
Applications
- General purpose switching and amplification
- Inverter and interface circuits
- Circuit driver stages
Procurement Notes
Verify the specific ordering suffix '315' against official Nexperia documentation to confirm manufacturing origin and compliance details. Ensure the SOT883 package variant matches the required footprint for PCB layout. Confirm that the integrated resistor configuration aligns with the target circuit's biasing requirements before finalizing procurement orders.
Selection Notes
Select this component when a compact NPN solution with fixed base biasing is required. The SOT883 package is suitable for high-density surface mount designs. Verify that the 47 kΩ internal resistor value meets the specific drive current needs of the application. Consider the 50 V voltage rating and 100 mA current limit to ensure adequate headroom for operational conditions.
Part Context
This part belongs to the PDTC144T series of NPN resistor-equipped transistors. The series includes various package options such as SOT23, SOT323, and TO-92. The TM suffix specifically denotes the SOT883 package type. All variants share identical electrical characteristics but differ in physical footprint and pinning configurations.
Replacement Considerations
Publicly confirmed substitutes within the same series include PDTA144TM (PNP complement). Other package variants like PDTC144TT or PDTC144TU offer equivalent electrical performance but require different PCB footprints. Direct pin-to-pin replacement is only possible with other SOT883 devices.
