Nexperia Resistor-Equipped NPN Transistor 100 mA 50 V DFN1110D-3 PDTC123JQBZ

The Nexperia PDTC123JQBZ is a resistor-equipped NPN transistor designed to simplify digital circuit design by integrating built-in bias resistors in a compact surface-mount DFN1110D-3 package. With a maximum DC collector current of 100 mA and a collector-emitter voltage rating of 50 V, this versatile device supports reliable, fast switching in applications such as logic-level signal amplification, load switching, and digital input control for microcontrollers and ICs.

Thanks to its integrated resistors, the PDTC123JQBZ significantly reduces required component count and assembly costs. Its ultra-low package height of only 0.5 mm makes it highly suitable for modern miniaturized electronics and high-density PCB assemblies where space is at a premium. The package facilitates automatic optical inspection (AOI) of solder joints, streamlining automated production processes.

Delivers a maximum DC collector current of 100 mA, ideal for driving moderate digital loads. Handles collector-emitter and collector-base voltages up to 50 V for flexible circuit compatibility. Optimized for surface mounting with a DFN1110D-3 (SOT8015) leadless package.

Features inbuilt resistors, reducing the need for additional biasing components and simplifying the overall circuit design. Low package profile allows integration into thin devices and stacked PCBs. Supports wide operating temperatures from -55°C to 150°C, meeting industrial reliability standards.

RoHS compliant and AEC-Q101 automotive qualified for demanding quality requirements. Provides a cost-effective, modern alternative to traditional BC857 family transistors in digital switching applications.

This transistor is widely used in industrial automation, automotive electronics, instrumentation, consumer electronics, and signal processing. Its robust design and digital signal compatibility make it especially well-suited for environments with densely packed circuits or space restrictions.

Typical use cases include controlling logic IC inputs, load switching in embedded systems, and driving low-power relays or LEDs. Whether for new designs or as a drop-in replacement, the Nexperia PDTC123JQBZ helps engineers save space, cut costs, and streamline the assembly process.
