• 150 °C TJ 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 122NQ.. 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 175 °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.
