Additional Details

The Vishay 40CPQ100-N3 is a dual Schottky rectifier with a repetitive peak reverse voltage of 100V and a forward current of 20A per diode (40A total). It's available in a TO-247AC package. The device's low forward voltage drop minimizes power loss, resulting in higher efficiency. Its high surge current capability ensures reliable operation under transient conditions. The dual common cathode configuration simplifies PCB layout and reduces the number of required components. The avalanche energy rating enhances circuit protection by allowing the rectifier to withstand transient overvoltage events.

The 40CPQ100-N3 is commonly used in server power supplies, telecom equipment, and industrial power converters. Its low forward voltage drop and fast switching speeds make it an excellent choice for high-frequency applications. The device is also RoHS compliant, meeting environmental standards for lead-free electronics.
