Product Description
Product Overview
The ROHM DTD143EK is an NPN digital transistor featuring built-in bias resistors (R1 = R2 = 4.7k). This integration simplifies circuit design by eliminating the need for external input resistors, enabling easy configuration of inverter circuits. The thin-film resistors offer complete isolation for negative input biasing and eliminate parasitic effects. Designed for straightforward operation, requiring only on/off condition settings, these transistors are suitable for switching, inverter, interface, and driver circuits. A complementary PNP type, DTB143EK, is also available. This product is Lead Free and RoHS Compliant.
