303CNQ100PbF

The 303CNQ100PbF is designed as one kind of schottky rectifiers with current of 300A. The 303CNQ... 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, plating power supplies, UPS systems, converters, freewheeling diodes, welding, and reverse battery protection.

303CNQ100PbF 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 303CNQ100PbF have been concluded into several points as follow. (1)Its maximum DC reverse voltage would be 100V. (2)Its maximum working peak reverse voltage would be 100V. (3)Its maximum average forward current see fig. 5 per leg would be 150A and per device would be 300A. (4)Its maximum peak one cycle non-repetitive surge current per leg see fig. 7 would be 22000A with the condition of 5s sine or 3s rect. pulse and would be 2500A with the condition of 10ms sine or 6ms rect. pulse. (5)Its  non-repetitive avalanche energy would be 15mJ. (6)Its repetitive avalanche current would be 1A. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of 303CNQ100PbF are concluded as follow. (1)Its maximum reverse leakage current  per leg would be 4.5mA at Tj=25°C and would be 80mA at Tj=125°C. (2)Its maximum junction capacitance per leg would be 4150pF. (3)Its typical series inductance per leg would be 6.0nH. At present we have not got so much information about this IC and we would try hard to get more information about it.
