Overview
The PDTA144EK,135 is a PNP resistor-equipped transistor from the PDTA144E series manufactured by NXP Semiconductors. It integrates two bias resistors within a single SOT346 (SC-59) surface-mounted package to simplify circuit design and reduce component count. The device features an input resistor R1 of 47 kΩ and a second resistor R2 of 47 kΩ. Key electrical characteristics include a maximum collector-emitter voltage (VCEO) of -50 V, a DC output current (IO) of -100 mA, and a total power dissipation of 250 mW at ambient temperatures up to 25 °C. The unit operates with a junction temperature range of -65 °C to +150 °C.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design and reduce overall component count.
- Reduces pick and place costs through consolidated packaging.
- Provides a compact solution for general purpose switching and amplification tasks.
Applications
- General purpose switching and amplification
- Inverter and interface circuits
- Circuit driver applications
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest documentation to confirm the exact package type and manufacturing origin. Ensure that the selected variant matches the required thermal resistance and pin configuration for the intended PCB layout. Cross-reference the datasheet revision date to guarantee compliance with current absolute maximum ratings and electrical characteristics before finalizing procurement specifications.
Selection Notes
Select the PDTA144EK when a PNP transistor with integrated biasing is required in a small surface-mount form factor. The SOT346 package offers a balance between leaded and fully surface-mount options. Verify that the 47 kΩ internal resistor values align with the target base drive requirements. Consider the 250 mW power dissipation limit and thermal resistance when designing for high ambient temperatures or dense board layouts.
Part Context
This component belongs to the PDTA144E series of PNP resistor-equipped transistors. The series includes multiple package variants such as SOT416, SOT490, SOT883, SOT54, SOT23, and SOT323, all sharing similar electrical characteristics but differing in physical dimensions and pinning arrangements. The PDTA144EK specifically utilizes the SOT346 outline.
Replacement Considerations
Consult the product overview table for direct complementary NPN types like PDTC144EK. Evaluate other PDTA144E series members if package constraints differ. Verify pinout compatibility and resistor ratios when substituting with generic discrete components or alternative manufacturers' equivalents.
