Schottky Rectifier, 5 A
50SQ...G Series
Vishay High Power Products
FEATURES
• 175 °C TJ operation
• Low forward voltage drop
• High frequency operation
• 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
• Designed and qualified for industrial level
DESCRIPTION
The 50SQ...G axial leaded Schottky rectifier series has been
optimized for low reverse leakage at high temperature. The
proprietary barrier technology allows for reliable operation up
to 175 °C junction temperature. Typical applications are in
switching power supplies, converters, freewheeling diodes,
and reverse battery protection.
