Overview
The PDTA144ET,235 is a PNP Resistor-Equipped Transistor (RET) from the Nexperia PDTA144E series, housed in an SOT23 surface-mounted package. It integrates a single PNP transistor with two built-in bias resistors: R1 (input/base) at 47 kΩ and R2 (base/emitter) at 47 kΩ. The device supports a maximum collector-emitter voltage (VCEO) of -50 V and an output current (IO) of -100 mA. Total power dissipation is rated at 250 mW at 25 °C ambient temperature. The component meets AEC-Q101 automotive qualification standards.
Feature Summary
- Integrates a PNP transistor with dual built-in bias resistors to simplify circuit design.
- Reduces printed circuit board space and component count compared to discrete resistor networks.
- Qualified for automotive applications under the AEC-Q101 standard.
- Offers cost-saving advantages through reduced pick-and-place operations.
Applications
- Digital switching circuits in automotive and industrial segments
- Control of integrated circuit inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix matches the required packaging configuration before procurement. Confirm that the SOT23 package variant aligns with the designated footprint on the target printed circuit board. Ensure compliance with reflow soldering requirements as specified in the manufacturer's thermal guidelines.
Selection Notes
Select this component when a compact PNP digital transistor solution is required for logic level switching. The integrated 47 kΩ resistors provide appropriate biasing for standard digital interfaces. Consider the SOT23 package dimensions and thermal dissipation limits relative to the available board space and operating temperature range.
Part Context
This part belongs to the PDTA144E family of PNP resistor-equipped transistors. Other variants in this series include the PDTA144EE (SOT416), PDTA144EM (SOT883), and PDTA144EU (SOT323). All share identical electrical characteristics but differ in physical package outline and thermal resistance properties.
Replacement Considerations
Direct pin-compatible replacements within the same family include PDTA144EE, PDTA144EM, and PDTA144EU. Cross-manufacturer equivalents should be verified against the specific 47 kΩ/47 kΩ resistor ratio and -50 V / -100 mA limiting values.
