The SS56C is a surface-mount Schottky barrier rectifier diode commonly used in power electronics for efficient rectification in low-voltage, high-current applications. It is designed for fast switching and low power loss, making it suitable for DC-DC converters, freewheeling, and polarity protection circuits.
It typically comes in a DO-214AB (SMC) package and is rated for around 5A average forward current with a reverse voltage rating of 60V, depending on the manufacturer variant.
Key Features
Schottky barrier technology (majority carrier conduction for fast switching)
Low forward voltage drop (improves efficiency and reduces heat loss)
High current capability (around 5A typical)
Reverse voltage rating up to 60V
High surge current capability (suitable for power spikes)
Low reverse recovery time (very fast switching behavior)
Low power loss / high efficiency operation
Guard ring structure for enhanced overvoltage protection
Surface-mount DO-214AB (SMC) package
High temperature reliability (typically up to 150°C junction temperature)
