| 20L15TSPBF Vishay High Power Products Schottky Rectifier, 20 A FEATURES * 125 C TJ operation (VR < 5 V) * Single diode configuration Base cathode 2 Available * Optimized for OR-ing applications * Ultra low forward voltage drop RoHS* COMPLIANT * Guard ring for enhanced ruggedness and long term reliability 1 N/C 3 Anode D2PAK * High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance * Lead (Pb)-free ("PbF" suffix) * Designed and qualified for Q101 level DESCRIPTION PRODUCT SUMMARY IF(AV) VR IRM 20 A 15 V 600 mA at 100 C The Schottky rectifier module has been optimized for ultra low forward voltage drop specifically for the OR-ing of parallel power supplies. 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.
