Overview
The STMicroelectronics 1N5822UB1 is an aerospace-grade Schottky rectifier designed for high-reliability applications. It features a 40 V repetitive peak reverse voltage and a 3 A average forward current capability. The device utilizes a surface-mount LCC-2B package, offering low forward voltage drop and minimal reverse leakage current. With a maximum operating junction temperature of +150 °C and a specified forward surge current rating, it supports robust performance in demanding power conversion environments.
Feature Summary
- Aerospace-grade construction ensuring high reliability and radiation tolerance
- Low forward voltage drop for improved efficiency in power circuits
- Surface-mount LCC-2B package optimized for automated assembly
Applications
- Switching mode power supplies
- High frequency DC to DC converters
- Low voltage high frequency inverters
- Free wheeling diode applications
Procurement Notes
Verify the specific engineering model designation and aerospace qualification status with the manufacturer before procurement. Confirm that the LCC-2B package dimensions match the target PCB footprint. Ensure that the component's radiation hardness meets the specific environmental requirements of the intended deployment scenario.
Selection Notes
Select this component when aerospace-grade reliability and high-temperature operation are required. Compare the LCC-2B package constraints against available board space. Evaluate the 40 V reverse voltage rating against the circuit's peak inverse voltage to ensure adequate safety margins under all operating conditions.
Part Context
This part belongs to the 1N5822 series of Schottky rectifiers from STMicroelectronics. It serves as the surface-mount aerospace variant of the through-hole 1N5822. The series is characterized by silicon carbide metal Schottky technology, providing superior switching characteristics compared to standard p-n junction rectifiers.
Replacement Considerations
The 1N5822UB1 is the direct surface-mount equivalent to the through-hole 1N5822. Verify pinout compatibility if replacing legacy designs. No other direct substitutes are confirmed in the provided documentation.
