The PDTC124EU is an NPN resistor-equipped transistor (RET) manufactured by Nexperia. It integrates two built-in bias resistors, each with a nominal resistance of 22kΩ, simplifying circuit design and reducing the need for external components.
This device features a maximum collector-emitter voltage (VCEO) of 50V and an output current capability of up to 100mA. With a typical transition frequency of 230MHz and maximum power dissipation of 200mW, it is suitable for digital signal control, load switching, and IC input control applications.
The PDTC124EU comes in a compact SC-70 (SOT323) three-pin surface-mount package measuring 2.0 × 1.25 × 0.95mm. Its integrated resistor configuration makes it a practical solution for industrial electronics, consumer electronics, and space-constrained electronic designs.
