PDTD113ZU-QX

Overview

The PDTD113ZU-QX is an NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia USA Inc. It integrates a single NPN bipolar junction transistor with built-in bias resistors in a compact SOT323 (SC-70) surface-mount package. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 500 mA, with a power dissipation rating of 200 mW. The integrated base resistor (R1) is 1 kOhm and the emitter resistor (R2) is 4.7 kOhm. It features a DC current gain (hFE) of at least 100 at 50 mA and 5 V, with a saturation voltage of 300 mV max at 2.5 mA base current and 50 mA collector current.

Feature Summary

• Integrates NPN transistor with dual bias resistors to simplify circuit design
• Reduces component count and PCB space requirements
• Qualified for automotive applications under AEC-Q101 standard
• Supports high-temperature operation up to 175 °C

Applications

• Controlling IC inputs
• Cost-saving alternative to discrete BC817 series in digital applications
• Switching loads

Procurement Notes

Verify the specific suffix -QX against official Nexperia documentation to confirm AEC-Q101 qualification status and exact pinout configuration. Ensure the ordering code matches the required tape-and-reel or cut-tape packaging format for automated assembly processes. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm active production status and availability.

Selection Notes

Select this component when space-constrained designs require integrated biasing for NPN switching applications. The SOT323 package offers a smaller footprint compared to standard SOT-23 variants. Verify that the 50 V breakdown voltage and 500 mA current capacity meet the specific load requirements. Confirm thermal management capabilities align with the 200 mW power dissipation limit in the target operating environment.

Part Context

This part belongs to the Nexperia PDTD113 series of Resistor-Equipped Transistors. The -QX suffix typically denotes automotive-grade qualification under AEC-Q101 standards. It serves as a complement to the PDTB113ZU PNP variant within the same product family, offering standardized biasing solutions for digital logic interfacing and load control tasks.
