• Low VF type of MA2Z720
• High rectification efficiency caused by its low forward-risevoltage (VF)
• Optimum for high-frequency rectification because of its short
reverse recovery time (trr)

Note) 1. Schottky barrier diode is sensitive to electric shock (static electricity, etc.). Due attention must be paid on the charge of a
human body and the leakage of current from the operating equipment.
