PDTA143ZE,115

Overview

The PDTA143ZE,115 is a PNP resistor-equipped transistor (RET) manufactured by NXP USA Inc. It integrates a single PNP bipolar junction transistor with built-in bias resistors in a compact SOT-323 surface-mount package. The device features a maximum collector-emitter voltage of 50 V and a continuous collector current rating of 100 mA. Internal resistance values are specified as R1 at 4.7 kOhms and R2 at 47 kOhms, providing a fixed bias ratio of 1:10. Key electrical characteristics include a minimum DC current gain (hFE) of 100 at Ic=10mA and Vce=5V, a maximum saturation voltage of 100mV at Ib=250µA and Ic=5mA, and a maximum power dissipation of 200 mW.

Feature Summary

• Integrates a PNP transistor with internal base and emitter bias resistors to simplify circuit design.
• Provides a fixed 1:10 bias resistor ratio for consistent switching performance.
• Utilizes an SOT-323 surface-mount package for space-constrained applications.

Applications

• Switching applications in portable consumer electronics
• Driver circuits for low-power loads in embedded systems
• Logic level translation and interface buffering

Procurement Notes

Verify the specific ordering code PDTA143ZE,115 against official NXP documentation to confirm the exact suffix designation and package variant. Ensure compatibility with RoHS3 compliance requirements and check for any recent production change notices (PCN) related to the SOT-323 package or manufacturing site before finalizing procurement specifications.

Selection Notes

Select this component when a PNP switching solution with integrated biasing is required to reduce external component count. The 50V rating and 100mA current capacity suit low-voltage digital logic interfaces. Compare the 4.7k/47k internal resistor values against application drive requirements to ensure adequate base current without exceeding saturation limits.
