ROHM DTC043ZUB User Guide
Summary
These integrated digital transistors feature built-in bias resistors, dramatically simplifying circuit design by eliminating the need for external input components. This manual provides comprehensive technical specifications, electrical characteristics, absolute maximum limits (up to 150 mW power dissipation), and detailed operational curves. Ideal for electronics designers who require a reliable NPN silicon switch for building stable inverters, high-precision interface circuits, or dedicated low-power drivers.
