Product Description

Product Overview

Digital Transistors with built-in bias resistors simplify circuit design by eliminating the need for external input resistors, enabling inverter circuit configurations. These transistors feature thin-film resistors with complete isolation for negative biasing and minimal parasitic effects, making them ideal for applications where only on/off conditions need to be set. Available in various package types including SOT-523, SOT-323, SOT-23-3L, and SOT-23.
