B 12/01 20TQ... 20TQ...S SCHOTTKY RECTIFIER 20 Amp IF(AV) = 19Amp VR = 35 to 45V Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM range IFSM @ tp = 5 s sine VF TJ @ 20 Apk, TJ = 125C range Description/ Features Units A V A V C The 20TQ Schottky rectifier series 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 are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection. 150 C TJ 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 20TQ 20 35 to 45 1800 0.51 - 55 to 150 Case Styles 20TQ... 20TQ...
