PRODUCT SUMMARY
IF(AV) VR 240 A 150 V
• Compliant to RoHS directive 2002/95/EC • Designed and qualified for industrial level
DESCRIPTION
The 249NQ150R 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.
