Mingjiada Electronics, with years of deep expertise in the semiconductor supply chain, now introduces the LEO1N5811AF brand-new original supply service to the market. Simultaneously, we offer premium buyback services for surplus inventory of this model, establishing an integrated “supply-recycling” solution to meet diverse customer needs.
Product Overview: LEO1N5811AF Radiation-Hardened Ultra-Fast Rectifier
The 6 A, 150 V ultra-fast rectifier LEO1N5811AF is a radiation-hardened rectifier housed in a miniature surface-mount SOD128Flat package, operating within a junction temperature range of -40 °C to +175 °C.
Based on STMicroelectronics' LEO universal specification for space-grade radiation-hardened plastic power discrete devices, this component meets stringent performance and reliability requirements for low-Earth orbit satellites within tight budgets. The specification complies with AEC-Q101 standards, balancing space savings, reduced cost of ownership, enhanced radiation resistance, and guaranteed high-volume production capability.
The LEO1N5811AF rectifier is suitable for switching power supplies and high-frequency DC-DC converters, such as low-voltage high-frequency inverters, OR loops, free-wheeling circuits, blocking diodes, or reverse polarity protection circuits. It is particularly well-suited for mission-critical systems like avionics and high-reliability industrial equipment.
Core Product Highlights: High Voltage, High Current + Radiation Resistance for Demanding Environments
STMicroelectronics' LEO1N5811AF is an ultra-fast recovery Schottky rectifier engineered for extreme environments. It integrates three core advantages—high voltage, high current, and radiation resistance—with performance parameters fully optimized for mission-critical applications:
• Key Electrical Performance: Rated reverse voltage up to 150V, forward average rectification current up to 6A, meeting rectification and freewheeling requirements for medium-to-high power circuits; ultra-fast recovery time and low forward voltage drop effectively reduce power loss and enhance circuit efficiency.
• Exceptional Radiation Resistance: Specially treated with anti-radiation processes, it delivers outstanding total dose irradiation (TID) tolerance. Maintains stable electrical parameters in radiation environments to prevent device failure, making it suitable for specialized applications like satellites, nuclear instruments, and radiation monitoring equipment.
• Compact and Reliable Packaging: Utilizes SOD128 flat-pack technology with a small footprint that minimizes PCB space requirements, enabling high-density layouts. Surface-mount technology facilitates automated production, offers robust mechanical stability, and provides excellent thermal performance, withstanding a wide operating temperature range from -55°C to +150°C.
• Comprehensive Quality Certifications: Complies with AEC-Q101 reliability standards, certified for aerospace applications (e.g., ESCC), free from SVHC substances, environmentally compliant, and suitable for high-reliability projects.
