Major Ratings and Characteristics IF(AV) Rectangular 18 A waveform VRRM range 35 to 45 V IFSM @ tp = 5 µs sine 1800 A VF @ 18 Apk, TJ = 125°C 0.53 V TJ range - 55 to 175 °C Characteristics 18TQ Units Description/Features The 18TQ Schottky rectifier 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 switching power supplies, converters, free-wheeling diodes, and re- verse battery protection. 175° 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 Bulletin PD-20178 rev.
