240 A
45 V
• 175 °C TJ operation
• 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.
