MBR0580S1-7 | Diodes Schottky rectifier | 80V 0.5A diode | SOD-123 diode
The MBR0580S1-7 is a 0.5A surface-mount Schottky barrier rectifier from Diodes Incorporated, delivering an 80V peak repetitive reverse voltage rating in the compact SOD-123 package. This low-voltage Schottky diode features a guard-ring die construction for enhanced transient and ESD immunity, achieving a typical forward voltage drop of just 0.69V at 0.5A to minimize conduction losses and improve conversion efficiency in power circuits. The device offers low leakage current of 0.5µA typical at full 80V reverse bias, total junction capacitance of 15pF at 5V reverse voltage, and a non-repetitive peak forward surge current of 14A for robust transient survival.
Applications
● AC-DC power supplies performing secondary-side rectification where low forward drop improves conversion efficiency.
● DC-DC converters requiring freewheeling and polarity-protection diodes in step-down and boost topologies.
● Reverse battery protection in portable and automotive electronics preventing damage from incorrect polarity installation.
● OR-ing of multiple supply voltages in redundant power systems where low-loss diode switching is critical.
● Solar panel blocking applications preventing reverse current flow and improving energy harvesting efficiency.
● LED lighting circuits requiring efficient current control and RFID tag energy-harvesting front-ends in space-constrained surface-mount designs.
FAQs
Q: Can MBR0580S1-7 handle capacitive loads? A: Yes, but derate current by 20% for capacitive loads per the datasheet recommendation to prevent thermal overstress.
Q: What is the surge current rating? A: 14A non-repetitive peak forward surge current for an 8.3ms single half sine-wave superimposed on rated load.
Q: Is the device suitable for automotive use? A: The standard version is commercial-grade; AEC-Q101-qualified automotive variants require direct contact with Diodes Incorporated for PPAP-capable parts.
