401CNQ045PbF

The 401CNQ045PbF is designed as one kind of schottky rectifier with current of 400A. The 401CNQ045PbF 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.

401CNQ045PbF has seven features. (1)175°C Tj operation. (2)Center tap module. (3)Low forward voltage drop. (4)High frequency operation. (5)Guard ring for enhanced ruggedness and long term reliability. (6)Lead (Pb)-free. (7)Designed and qualified for industrial level. Those are all the main features.

Some absolute maximum ratings of 401CNQ045PbF have been concluded into several points as follow. (1)Its maximum DC reverse voltage would be 45V. (2)Its maximum working peak reverse voltage would be 45V. (3)Its maximum average forward current per leg would be 200A and per device would be 400A. (4)Its maximum peak one cycle non-repetitive  surge current per leg would be 25000A with the condition of 5s sine or 3s rect. pulse and would be 3450A with the condition of 10ms sine or 6ms rect. pulse. (5)Its non-repetitive avalanche energy per leg would be 270mJ. (6)Its repetitive avalanche current per leg would be 40A. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of 401CNQ045PbF  are concluded as follow. (1)Its maximum reverse leakage current per leg see fig. 2 would be 20mA at Tj=25°C and would be 180mA at Tj=125°C. (2)Its maximum junction capacitance per leg would be 10300pF. At present we have not got so much information about this IC and we would try hard to get more information about it.
