203DMQ080

The 203DMQ080 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 junction temperature. Typical applications of 203DMQ are in high current switching power supplies, plating power supplies,UPS systems, converters, free-wheeling diodes, welding, and reverse battery
protection.

The 203DMQ080 has six features.The first one is 175 TJ operation.The second one 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 is high frequency operation.The sixth one is guard ring for enhanced ruggedness and long term reliability.

The 203DMQ080 has some absolute maximum ratings.When parameter is IF(AV) Max. average forward (Per Leg) current(Per Device),the limits is 200,the units is A,the condition is 50% duty cycle @ TC = 107, square wave form.When parameter is IFSM Max. peak one cycle non-repetitive surge current (Per Leg),the limits is 16,000,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 (Per Leg),the limits is 2,100,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 limits is 15,the units is mJ,the condition is TJ = 25, IAS=1 Amps,L=30 mH.When parameter is IAR repetitive avalanche current,the limits is 1,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.
