Product Overview

The DIGITAL TRANSISTOR (NPN) features built-in bias resistors, simplifying inverter circuit configuration without external input resistors. These thin-film resistors offer complete isolation for negative input biasing and minimize parasitic effects. Operation is streamlined by only requiring the setting of on/off conditions, making device design easier. These transistors are suitable for applications where simplified design and reliable switching are paramount.
