PDTB113ZUX

Overview

The PDTB113ZUX is a PNP Resistor-Equipped Transistor (RET) from the PDTB1xxxU series, manufactured by Nexperia. It is housed in a SOT323 (SC-70) surface-mounted plastic package with three leads. The device features a collector-emitter voltage (VCEO) of -50 V and an output current (IO) capability of -500 mA. It integrates two bias resistors: R1 (input) is nominally 1 kΩ, and R2 (base-emitter) is nominally 10 kΩ, resulting in a typical resistor ratio of 10. The component supports high-temperature applications up to 175 °C and is qualified under AEC-Q101 standards for automotive use.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count
• Provides ±10% resistor ratio tolerance for consistent performance
• Qualified for high-temperature applications up to 175 °C
• AEC-Q101 qualified for automotive electronics reliability

Applications

• Controlling IC inputs
• Switching loads
• Cost-saving alternative to BC807 or BC817 series transistors in digital applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct resistor values and marking codes. Confirm that the SOT323 package dimensions align with the target PCB footprint requirements. Check for any recent revision updates to the data sheet to ensure compliance with current manufacturing specifications.

Selection Notes

Select this component when a compact PNP transistor solution with integrated biasing is required for space-constrained designs. Ensure the application voltage does not exceed the -50 V collector-emitter rating. Consider the thermal resistance characteristics if operating near the maximum junction temperature limit of 175 °C.

Part Context

This part belongs to the PDTB1xxxU series of PNP resistor-equipped transistors. It serves as the PNP complement to the NPN PDTD113ZU device within the same family. All variants in this series share the identical SOT323 package and general electrical characteristics, differing primarily in the internal resistor network configurations.

Replacement Considerations

The PDTB113EU is a variant within the same series featuring different resistor values (R1=1kΩ, R2=1kΩ). Verify functional compatibility before substitution, as the internal bias network differs significantly from the PDTB113ZUX configuration.
