Overview
The PDTA144EU,135 is a PNP Resistor-Equipped Transistor (RET) from the PDTA144E series, manufactured by Nexperia USA Inc. It integrates a single PNP transistor with built-in bias resistors R1 and R2, both typically 47 kΩ, into a SOT323 (SC-70) surface-mount package. The device supports an output current of -100 mA and withstands a collector-emitter voltage of -50 V. Key electrical characteristics include a DC current gain (hFE) minimum of 80 at -5 mA/-5 V, a transition frequency (fT) of 180 MHz, and a total power dissipation of 200 mW at 25 °C ambient temperature.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design and reduce component count.
- Qualified for automotive applications in accordance with AEC-Q101 standards.
- Provides a cost-saving alternative to discrete BC847/857 series transistors in digital switching applications.
Applications
- Digital applications in automotive and industrial segments
- Control of IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current product database to confirm availability and packaging configuration. Confirm that the SOT323 package variant matches the required footprint for the target PCB layout. Ensure compliance with RoHS directives and REACH regulations as specified in the latest datasheet revision before finalizing procurement specifications.
Selection Notes
Select this component when a compact PNP solution with integrated base biasing is required for space-constrained designs. The SOT323 package offers a very small form factor suitable for high-density mounting. Consider the 47 kΩ input resistance and the specific saturation voltage characteristics for interface compatibility with driving logic levels.
Part Context
This part belongs to the PDTA144E series of PNP resistor-equipped transistors. The 'EU' designation specifically identifies the SOT323 (SC-70) plastic surface-mounted package variant. It serves as the PNP complement to the PDTC144EU NPN RET family member within the same product line.
Replacement Considerations
PDTC144EU is the NPN complement within the same series. Other package variants in the PDTA144E family include PDTA144ET (SOT23), PDTA144EE (SOT416), and PDTA144EM (SOT883). Verify pinout compatibility if substituting between different package types.
FAQ
