Overview
The PDTA144VU,115 is a PNP resistor-equipped transistor from the PDTA144V series manufactured by Nexperia. It integrates bias resistors to simplify circuit design and reduce component count. The device features a collector-emitter voltage (VCEO) of -50 V and a continuous output current (IO) of -100 mA. The internal input bias resistor (R1) has a typical value of 47 kΩ with a range of 33 kΩ to 61 kΩ. The bias resistor ratio (R2/R1) typically measures 0.21. Packaged in the SOT323 (SC-70) surface-mount format, it supports an ambient temperature range of -65 °C to +150 °C.
Feature Summary
- Built-in bias resistors for simplified circuit design
- Reduces overall component count
- Reduces pick and place manufacturing costs
Applications
- General purpose switching and amplification
- Circuit drivers
- Inverter and interface circuits
Procurement Notes
Verify the specific ordering suffix matches the required tape-and-reel packaging configuration. Confirm that the SOT323 package variant aligns with the target PCB footprint requirements. Ensure the sourcing channel provides valid traceability documentation consistent with Nexperia's product data sheet standards.
Selection Notes
Select this component when a compact PNP solution with integrated base biasing is required. The fixed R1 value of 47 kΩ suits standard logic drive levels. Verify that the -50 V collector-emitter rating meets the maximum voltage stress conditions of the application environment.
Part Context
This part belongs to the PDTA144V series of PNP resistor-equipped transistors. It serves as the NPN complement counterpart to the PDTC144VU. The series includes various package options such as SOT416, SOT346, SOT883, SOT54, SOT23, and SOT323, allowing flexibility in board layout constraints while maintaining identical electrical characteristics across the family.
