Diotec digital bipolar transistors, available from ELTRON, are ready-to-use components designed for simple and cost-effective digital circuits. Thanks to built-in base and pull-down resistors (R1 and R2), they simplify PCB design and reduce the number of external passive components.
The range includes NPN and PNP transistors with collector-emitter voltages ranging from 50 V to 60 V and collector currents from 30 mA to 800 mA. These components are suitable for control circuits, TTL/CMOS logic applications and as drivers in low-power circuits. The power dissipation is in the range of 0.15–0.25 W, making them ideal for compact, energy-efficient designs.
Two built-in polarisation resistors (e.g. 4.7kΩ, 22kΩ, 47kΩ) ensure consistent transistor behaviour under pulse conditions. Available SMD packages – SOT-23, SOT-323, SOT-363 and SOT-523 – allow for easy integration into automated production.
Thanks to a wide selection of configurations and resistor values, Diotec digital bipolar transistors available from ELTRON are the optimal solution for electronics manufacturers, system integrators and device designers in the fields of automation, IoT and consumer electronics.
