444CNQ035

The 444CNQ035 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 125 junction temperature. Typical applications of 444CNQ035 are in high current switching power supplies, plating power supplies, UPS systems, converters, free-wheeling diodes,welding, and reverse battery protection.

The 444CNQ035 has six features.The first one is 125 TJ operation.The second one of 444CNQ035 is center tap module.The third one is high purity,high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance.The fourth one is low forward voltage drop.The fifth one of 444CNQ035 is high frequency operation.The last one is guard ring for enhanced ruggedness and long term reliability.

The 444CNQ035 has some absolute maximum ratings.When parameter is IF(AV) Max. average forward current,the limits is 440,the units is A,the condition is 50% duty cycle @ TC =81, square wave form.When parameter is IFSM Max. peak one cycle non-repetitive surge current,the limits is 35,000,the units is A,the condition is 5s sine or 3s rect.pulse following any rated load condition and with rated VRRM applied.When parameter is IFSM Max. peak one cycle non-repetitive surge current ,the limits is 3800,the units is A,the condition is 10ms Sine or 6ms rect.pulse following any rated load condition and with rated VRRM applied.When parameter is EAS non-repetitive avalanche energy,the limit is 270,the units is mJ,the condition is TJ = 25 , IAS = 40 Amps, L = 0.34 mH.When parameter of 444CNQ035 is IAR repetitive avalanche current,the limit is 40,the units is A,the condition is current decaying linearly to zero in 1 sec frequency limited by TJ max. VA = 1.5 x VR typical.
