40CPQ050 Description

Short technical summary and product information.

The 40CPQ050 is a Schottky rectifier diode array from Vishay Dale, configured as a pair of common cathode diodes. It is designed for high efficiency power conversion applications requiring low forward voltage drop and fast switching. The device is rated for a maximum DC reverse voltage of 50V and can handle an average rectified current of 20A per leg (40A total) with a 50% duty cycle at a case temperature of 120°C. Forward voltage drop is typically 530mV at 20A and 25°C, dropping to 490mV at 125°C. The junction operating temperature range is -55°C to 150°C. The TO-247-3 (TO-247AC) through-hole package provides excellent thermal performance, with a junction-to-case thermal resistance of 1.25°C/W per leg. The device features a guard ring for enhanced ruggedness and long-term reliability, and is suitable for high-frequency operation. Typical applications include switching power supplies, DC-DC converters, freewheeling diodes, and reverse battery protection circuits.
