Schottky Rectifier, 1.0 A
STPS1L30UPbF
Vishay High Power Products
FEATURES
• Small foot print, surface mountable
• Very low forward voltage drop
• High frequency operation
• Guard ring for enhanced ruggedness and long term
reliability
• Lead (Pb)-free (“PbF” suffix)
• Designed and qualified for industrial level
DESCRIPTION
The STPS1L30UPbF surface mount Schottky rectifier
has been designed for applications requiring low
forward drop and small foot prints on PC board. Typical
applications are in disk drives, switching power supplies,
converters, freewheeling diodes, battery charging, and
reverse battery protection.
