The proprietary barrier technology allows for reliable operation up to 150° C junction temperature. Typical applications are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection. 150° C T J operation High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability Description/ Features IF(AV) = 19Amp VR = 35 to 45V Case Styles 20TQ...
