Fairchild SB120 - SB1100 Data Handbook
Summary
These Schottky Rectifiers are essential components for reliable power conversion across various demanding applications. Designed for low voltage and high-frequency operation, they ensure stable rectification in environments such as inverters, free wheeling circuits, and DO-41 protective systems. This manual provides comprehensive technical specifications, covering everything from absolute maximum ratings and thermal dissipation profiles to detailed electrical performance curves (forward voltage, reverse current) across a wide operational range of -65 to +125°C. Ideal for power electronics engineers needing high-performance, durable rectifying components.
