DESCRIPTION PRODUCT SUMMARY
IF(AV) VR IRM 2 x 20 A 15 V 600 mA at 100 C
The MBR40L15CW center tap 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.
