Additional Details

The HERA808G C0G is typically packaged in a DO-27 or similar axial-leaded package. It is designed to handle a significant average forward current (typically around 8A depending on the exact specifications). The reverse recovery time is a critical parameter, usually specified in the nanosecond range. The C0G suffix might refer to specific manufacturing or testing standards. The operating temperature range usually extends from -65°C to +175°C, making it suitable for demanding environments. Always refer to the manufacturer's datasheet for precise electrical characteristics like maximum repetitive reverse voltage, forward voltage at specific currents, and surge current ratings. RoHS compliance ensures the device is free from hazardous substances.
