Product Description
Product Overview
The ROHM DTD123YK is an NPN digital transistor featuring built-in bias resistors, enabling simplified circuit design for inverter and switching applications without external resistors. This design facilitates easy configuration of inverter circuits and allows for negative input biasing due to the thin-film resistors with complete isolation, eliminating parasitic effects. It is suitable for switching, inverter, interface, and driver circuits. Complementary PNP type is DTB123YK. This product is Lead Free and RoHS Compliant.
