Product overview
Description
The 1 A, 45 V Schottky diode LEO1N5819 is a rad-hard rectifier housed in the tiny surface-mount SOD128Flat package, operating with a junction temperature from -40 °C to +150 °C.
The LEO1N5819 meets the challenges of the LEO satellites for performance and reliability in a strict budget thanks to the STMicroelectronics LEO generic specification dedicated to space ready rad-hard plastic power discretes; this AEC-Q101-based specification offers a trade-off among foot-print size savings and cost of ownership together with radiation hardness and large production capacity.
The LEO1N5819 rectifier is suitable for switching mode power supplies and high frequency DC-to-DC converters such as low voltage high frequency inverter, OR-ring, free-wheeling, blocking diode or reverse polarity protection. It is well suited for critical mission equipment such as avionics and Hi-Rel industrial.
