Product Overview

The DTC143ZUA is an NPN transistor featuring built-in bias resistors, simplifying inverter circuit configurations by eliminating the need for external input resistors. These thin-film bias resistors offer complete isolation for positive input biasing and minimize parasitic effects. The device is designed for ease of use, requiring only the setting of on/off conditions for operation. It is housed in a SOT-323 plastic-encapsulate package.
