440CNQ030PbF

The 440CNQ030PbF is designed as one kind of schottky rectifiers with current of 440A. The 440CNQ030PbF center tap, high current, schottky rectifier module has been optimized for very low forward voltage drop, with moderate leakage. The proprietary barrier technology allows for reliable operation up to 150°C junction temperature. Typical applications of the 440CNQ030PbF are in switching power supplies, converters, freewheeling diodes, welding and reverse battery protection.

440CNQ030PbF has seven features. (1)150°C Tj operation. (2)Center tap module. (3)Very low forward voltage drop. (4)High frequency operation. (5)Guard ring for enhanced ruggedness and long term reliability. (6)Lead (Pb)-free ("PbF" suffix). (7)Designed and qualified for industrial level. Those are all the main features.

Some absolute maximum ratings of the 440CNQ030PbF have been concluded into several points as follow. (1)Its maximum DC reverse voltage would be 30V. (2)Its maximum working peak reverse voltage would be 30V. (3)Its maximum average forward current per module would be 440A and per leg would be 220A. (4)Its maximum peak one cycle non-repetitive surge current per leg would be 27000A at 5s sine or 3s rect. pulse and would be 3000A at 10ms sine or 6ms rect. pulse. (5)Its  non-repetitive avalanche energy per leg would be 198mJ. (6)Its repetitive avalanche current per leg would be 44A. 440CNQ030PbF should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of 440CNQ030PbF are concluded as follow. (1)Its maximum reverse leakage current per leg would be 20mA at Tj=25°C and would be 1120mA at Tj=125°C. (2)Its maximum junction capacitance per leg would be 14800pF. (3)Its typical series inductance per leg would be 5nH. At present we have not got so much information about this IC and we would try hard to get more information about 440CNQ030PbF.
