Product Description

Product Overview

The DTD543Z series are low V_CE(sat) digital transistors designed for applications requiring efficient switching and reduced power loss. Featuring built-in bias resistors, these transistors simplify circuit configuration, particularly for inverter circuits, by eliminating the need for external input resistors. Their thin-film bias resistors offer complete isolation and minimize parasitic effects, making them suitable for INVERTER, INTERFACE, and DRIVER applications.
