Additional Details

The EFM102 typically has a reverse voltage rating of around 100V and a forward current rating of 1A. The fast recovery time is typically in the nanosecond range. The operating junction temperature ranges from -65°C to +150°C. The forward voltage drop is typically around 0.9V at the rated current. The surge current capability is significantly higher than the average forward current rating, providing protection against transient events. The surface mount package simplifies assembly and allows for automated manufacturing processes. Detailed specifications, including leakage current, thermal resistance, and recovery time characteristics, are available in the Rectron Semiconductor datasheet.
