PDTC124XE/DG/B2115

Overview

The PDTC124XE/DG/B2115 is an NPN resistor-equipped transistor manufactured by NXP Semiconductors. It integrates a single NPN bipolar junction transistor with built-in bias resistors in a compact SC-75 (SOT363) surface-mount package. The device features a maximum collector current of 0.1 A and a collector-emitter voltage rating of 50 V. It offers a minimum DC current gain (hFE) of 60 and supports operating temperatures up to 150 °C. The component is lead-free, RoHS compliant, and classified under EAR99.

Feature Summary

• Integrates NPN transistor with built-in bias resistors for simplified circuit design
• Compact SC-75 plastic surface-mount package for space-constrained applications
• High thermal stability with maximum operating temperature of 150 °C
• Lead-free construction compliant with RoHS standards

Applications

• Switching applications requiring integrated biasing
• Driver circuits for low-power loads
• Logic level translation interfaces
• General-purpose amplification stages

Procurement Notes

Verify the exact ordering part number against the manufacturer's official database to ensure correct suffix alignment. Confirm that the SC-75 package variant matches the specific reel or tape-and-reel configuration required for automated assembly processes. Cross-reference the manufacturing date code and quality certifications with the latest datasheet revision to guarantee compliance with current environmental and safety regulations.

Selection Notes

Select this component when a discrete NPN transistor solution with integrated base biasing is preferred over external resistor networks. The SC-75 package is suitable for high-density PCB layouts where board space is limited. Ensure the application current remains within the 0.1 A limit and voltage stresses do not exceed 50 V. Consider the 150 °C junction temperature capability for environments with elevated thermal loads.

Part Context

This part belongs to NXP's family of resistor-equipped transistors, which combine passive and active components into a single package. These devices are designed to reduce component count and simplify assembly compared to discrete solutions. The PDTC124XE series specifically utilizes an NPN configuration with a fixed bias resistor ratio, offering a standardized alternative to custom discrete designs in consumer and industrial electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with equivalent NPN resistor-equipped transistors from other manufacturers based on pinout, electrical ratings, and package dimensions before substitution.
