| 401CNQ...PbF Series Vishay High Power Products Schottky Rectifier, 400 A FEATURES * 175 C TJ operation Lug terminal anode 1 Lug terminal anode 2 * Center tap module * Low forward voltage drop * High frequency operation * Guard ring for enhanced ruggedness and long term reliability TO-244 Base common cathode * Lead (Pb)-free * Designed and qualified for industrial level DESCRIPTION PRODUCT SUMMARY IF(AV) VR 400 A 40/45 V The 401CNQ... center tap 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, converters, freewheeling diodes, welding and reverse battery protection.
