Schottky Rectifier, 2 x 20 A

40CPQ050PbF/40CPQ060PbF

Vishay High Power Products

FEATURES

• Center tap TO-247 package

• Very 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 (“PbF” suffix)

• Designed and qualified for industrial level

DESCRIPTION

The 40CPQ...PbF center tap Schottky rectifier has been

optimized for very low forward voltage drop with moderate

leakage. The proprietary barrier technology allows for

reliable operation up to 150 °C junction temperature. Typical

applications are in switching power supplies, converters,

freewheeling diodes, and reverse battery protection.
