PDTA113EE,115

Overview

The PDTA113EE,115 is a single NPN digital transistor manufactured by NXP Semiconductors. It integrates a single NPN bipolar junction transistor with an internal base bias resistor network within a compact SOT-323 (SC-70) surface-mount package. The device is designed for switching and amplification applications requiring simplified circuit design through integrated pull-up/pull-down resistors. Key electrical specifications include a maximum collector-emitter voltage of 50 V and a maximum DC collector current of 100 mA. The component operates within a temperature range of -40 °C to +150 °C and complies with RoHS directives.

Feature Summary

• Integrated NPN transistor with built-in base biasing resistors
• Compact SOT-323 surface-mount packaging for space-constrained designs
• High thermal stability supporting operation up to 150 °C

Applications

• General-purpose logic level shifting and switching
• Pull-up or pull-down resistor replacement in digital circuits
• Driver stages for LEDs and small loads

Procurement Notes

Verify the specific suffix '115' corresponds to the standard tape-and-reel packaging configuration when sourcing from distributors. Confirm that the requested quantity aligns with the manufacturer's standard reel size to avoid partial reel handling fees. Ensure the procurement channel provides traceability documentation consistent with NXP's quality standards for automotive or industrial grade components if required by the application.

Selection Notes

Select this component when a single NPN switch with fixed biasing is required to reduce external component count. Compare the internal resistance values against the target logic family voltage levels to ensure proper saturation. Consider the SOT-323 footprint constraints during PCB layout. Verify that the 100 mA current rating meets the load requirements without exceeding thermal limits in the intended enclosure environment.

Part Context

This part belongs to NXP's PDTAxxxE series of pre-biased transistors. These devices are engineered to replace discrete resistor-transistor combinations, thereby saving board space and assembly costs. The 'EE' designation typically indicates specific internal resistor ratios optimized for standard logic interfaces. This series is widely used in consumer electronics and industrial control panels where reliability and miniaturization are critical.

Replacement Considerations

Direct replacements include the BC847E,115 or similar NPN digital transistors in SOT-323 packages from other manufacturers, provided the internal resistor values and breakdown voltages match the original design specifications. Always verify pinout compatibility and thermal characteristics before substituting.
