FEATURES
• Low profile, axial leaded outline
• High frequency operation
• Very low forward voltage drop
• High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
• Guard ring for enhanced ruggedness and long term
reliability
• Lead (Pb)-free plating
• Designed and qualified for industrial level
DESCRIPTION
The 11DQ.. axial leaded Schottky rectifier has been
optimized for very low forward voltage drop, with moderate
leakage. Typical applications are in switching power
supplies, converters, freewheeling diodes, and reverse
battery protection.
