ROHM DTD543EMT2L Digital Transistor

The DTD543E series are low VCE saturation digital transistors with built-in resistors, designed for high-efficiency switching in inverter, interface, and driver circuits. Featuring lower VCE(sat) than conventional counterparts, these compact devices integrate thin-film bias resistors, allowing circuits to be configured without external resistors, which improves performance and simplifies design. Suitable for various industrial applications, they operate at a maximum collector current of 500mA and a voltage of 12V. These transistors come in SOT-723 and SOT-416 packages, ensuring reliable operation in compact spaces, with low on-resistance and high transition frequency for optimized switching performance.
