Schottky Rectifier, 240 A

241NQ045R

Vishay High Power Products

FEATURES

• Unique high power, HALF-PAK module

• Replaces four parallel DO-5’s

• Easier to mount and lower profile than DO-5’s

• High purity, high temperature epoxy encapsulation for

enhanced mechanical strength and moisture resistance

• Low forward voltage drop

• High frequency operation

• Guard ring for enhanced ruggedness and long term

reliability

• Compliant to RoHS directive 2002/95/EC

• Designed and qualified for industrial level

DESCRIPTION

The 241NQ045R high current Schottky rectifier module 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.
