Overview
The PDTA144TU,115 is a PNP resistor-equipped transistor manufactured by Nexperia in the SOT323 (SC-70) surface-mount package. It integrates a single NPN complement counterpart and features a built-in bias resistor R1 of 47 kΩ with R2 left open. The device supports a maximum collector-emitter voltage (VCEO) of -50 V and a continuous DC output current (IO) of -100 mA. Thermal resistance from junction to ambient is specified at 625 K/W for this package. Operating temperatures range from -65 °C to +150 °C.
Feature Summary
- Integrates a 47 kΩ bias resistor to simplify circuit design and reduce component count
- Eliminates external base drive components to lower pick-and-place costs
- Provides a compact surface-mount solution for general-purpose switching applications
Applications
- General purpose switching and amplification
- Inverter and interface circuits
- Circuit driver stages
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact manufacturing origin and compliance status. Confirm that the SOT323 package variant matches the required footprint for the target PCB layout. Ensure all technical specifications align with the system requirements before finalizing procurement orders.
Selection Notes
Select this component when a PNP transistor with an integrated base resistor is required for space-constrained designs. The SOT323 package offers a small form factor suitable for high-density boards. Verify that the -50 V voltage rating and -100 mA current limits are sufficient for the intended load conditions and operating environment.
Part Context
This part belongs to the PDTA144T series of PNP resistor-equipped transistors. The series includes various package options such as SOT23, SOT346, and SOT883. The TU suffix specifically denotes the SOT323 plastic surface-mounted package configuration used in this product data sheet.
Replacement Considerations
Direct substitutes within the same series include PDTA144TT (SOT23) and PDTA144TK (SOT346). These alternatives share identical electrical characteristics but differ in physical package dimensions and pinout orientation. Verify mechanical compatibility before substitution.
