The proprietary barrier technology allows for reliable operation up to 125 °C junction temperature. Typical applications are in parallel switching power supplies, converters, reverse battery protection, and redundant power subsystems. 125°C TJ operation (VR < 5V) Single diode configuration Optimized for OR-ing applications Ultra low forward voltage drop Guard ring for enhanced ruggedness and long term reliability High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Values 20 15 700 0.25 - 55 to 125 °C Case Styles 20L15T 20L15TS Base Cathode Base Cathode 2 1 3 1 3 Cathode Anode N/C Anode TO-220AC www.irf.com D2PAK 1 20L15T, 20L15TS Bulletin PD-20577 rev.
