Product Description
Product Overview
The DTB143EK is a digital transistor featuring built-in bias resistors, simplifying inverter circuit configurations without the need for external input resistors. Its thin-film bias resistors offer complete isolation for positive input biasing and minimize parasitic effects. Designed for ease of use, it requires only setting the on/off conditions for operation. This device is suitable for applications such as inverters, interfaces, and drivers.
