Polarity Marking
Handling Precaution
Schottky barrier diodes are having large-reverse-current-leakage characteristic compare to other rectifier
products. This current leakage and not proper operating temperature or voltage may cause thermal run.
Please take forward and reverse loss into consideration when you design.
