PDTA115EU,115

Overview

The PDTA115EU,115 is a PNP resistor-equipped transistor (RET) manufactured by Nexperia USA Inc. It integrates two bias resistors within a single SOT-323 (SC-70) surface-mount package. The device features a collector-emitter voltage (VCEO) of -50 V and a DC output current (IO) of -20 mA. Internal resistance values are specified as R1 = 100 kΩ and R2 = 100 kΩ. The component supports an operating ambient temperature range from -65 °C to +150 °C with a maximum junction temperature of 150 °C. Total power dissipation in the SOT-323 package is rated at 200 mW at 25 °C.

Feature Summary

Selection Notes

Select this component for designs requiring a compact PNP switching solution with integrated base biasing. The SOT-323 package offers space efficiency compared to discrete resistor-transistor combinations. Ensure the required input resistance ratio aligns with the fixed 1:1 internal configuration provided by the 100 kΩ resistor pair.

Part Context

This part belongs to the PDTA115E series of NXP/Nexperia PNP resistor-equipped transistors. It serves as the PNP complement to the PDTC115EU NPN variant. The series includes multiple package options such as SOT23, SOT416, and SOT883, but the EU suffix specifically denotes the SOT-323 form factor.

Replacement Considerations

Direct functional substitutes include the PDTC115EU for NPN logic inversion requirements. Other packages within the same electrical family, such as PDTA115ET (SOT23), may be considered if footprint changes are permissible.
