Product Description

Product Overview

The LDTC143XLT1G is a NPN Silicon Surface Mount Transistor featuring a monolithic bias resistor network. This integrated design simplifies circuit configuration, enabling the use of inverter circuits without external input resistors. The built-in thin-film resistors offer complete isolation for positive input biasing and minimize parasitic effects, making device design easier by requiring only on/off condition settings. It is suitable for inverter, interface, and driver applications.
