LEO1N5819AF Integrated Circuit Chip Rad-hard 45V 1A Schottky Rectifier

The LEO1N5819AF is a 1A, 45V radiation-hardened Schottky diode rectifier housed in the compact SOD128Flat surface-mount package. Operating within a junction temperature range of -40°C to +150°C, this component is specifically engineered for Low Earth Orbit (LEO) satellite applications where performance, reliability, and cost-effectiveness are critical.

Product Overview

Designed to meet STMicroelectronics' LEO generic specification for space-ready radiation-hardened plastic power discretes, this AEC-Q101-based solution offers an optimal balance between footprint size reduction, cost efficiency, radiation hardness, and manufacturing scalability. The LEO1N5819AF is ideal for switching mode power supplies, high-frequency DC-to-DC converters, low-voltage high-frequency inverters, OR-ring applications, free-wheeling circuits, blocking diodes, and reverse polarity protection in critical mission equipment including avionics and high-reliability industrial systems.
