PDTC114YU/ZLX

Overview

The PDTC114YU is an NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia, housed in a compact SOT323 (SC-70) surface-mounted device plastic package. It integrates a single NPN transistor with built-in bias resistors: R1 is 10 kΩ and R2 is 47 kΩ. The device supports a maximum collector-emitter voltage of 50 V and provides an output current capability of 100 mA. Key electrical characteristics include a DC current gain (hFE) of at least 100 at IC = 5 mA, a transition frequency (fT) of 230 MHz, and a total power dissipation of 200 mW at 25 °C ambient temperature.

Feature Summary

• Integrates an NPN transistor with built-in bias resistors to simplify circuit design
• Reduces component count and pick-and-place costs compared to discrete solutions
• Operates within a wide ambient temperature range from -65 °C to 150 °C

Applications

• Digital applications in industrial segments
• Cost-saving alternative for BC847 series in digital applications
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details such as reel size or tape width. Confirm that the requested part number matches the exact resistor values and package type required for the design. Ensure compliance with the non-automotive qualification status if the application does not require AEC-Q101 certification.

Selection Notes

Select this component when space constraints favor the SOT323 package over larger alternatives. The integrated 10 kΩ input resistor and 47 kΩ pull-down resistor are suitable for standard logic interface applications. Verify that the 100 mA current rating meets the load requirements and that the 50 V breakdown voltage exceeds the maximum operating voltage.

Part Context

This device belongs to the PDTC114Y family of NPN resistor-equipped transistors. It serves as the NPN counterpart to the PDTA114YU PNP RET. The product is designed for general-purpose switching and logic interfacing tasks where board space and assembly efficiency are prioritized.

Replacement Considerations

Direct functional replacements within the same family include other variants of the PDTC114Y series with different resistor ratios. For discrete equivalents, verify pinout compatibility and ensure the replacement transistor meets the 50 V VCEO and 100 mA IO specifications.
