Schottky Rectifier, 120 A

120NQ045PbF

Vishay High Power Products

FEATURES

• 150 °C T

operation

• Low forward voltage drop

• High frequency operation

• Guard ring for enhanced ruggedness and long

term reliability

• Lead (Pb)-free

• Designed and qualified for industrial level

DESCRIPTION

The 120NQ.. high current Schottky rectifier module series

has been optimized for low reverse leakage at high

temperature. The proprietary barrier technology allows for

reliable operation up to 150 °C junction temperature. Typical

applications are in high current switching power supplies,

plating power supplies, UPS systems, converters,

freewheeling diodes, welding, and reverse battery

protection.
