The 40CPQ035 from Vishay is a Schottky rectifier diode array configured as 1 pair common cathode. It is designed for high efficiency power conversion applications requiring low forward voltage drop and fast switching. The device offers a maximum DC reverse voltage rating of 35 V and an average forward current of 40 A per package under rated conditions. Forward voltage drop is typically 0.49 V at 20 A and 25 °C junction temperature, decreasing to 0.43 V at 125 °C, enabling low conduction losses. The diode exhibits a reverse leakage current of 4 mA at 35 V and 25 °C, and a junction capacitance of 1850 pF per leg, supporting high frequency operation.
This diode array is housed in a TO-247-3 (TO-247AC) through-hole package with a typical weight of 6 g. It features a maximum junction temperature rating of 150 °C and thermal resistance junction-to-case of 1.25 °C/W per leg. The device is suitable for use in switching power supplies, DC-DC converters, free-wheeling diode circuits, and reverse battery protection. The guard ring design enhances ruggedness and long-term reliability.
The maximum DC reverse voltage (Vr) is 35 V.
The maximum average forward current (Io) is 40 A per package, under 50% duty cycle rectangular waveform at case temperature 120 °C.
The maximum forward voltage drop is 0.49 V at 20 A (per leg) at 25 °C junction temperature, and 0.43 V at 20 A at 125 °C.
The device is packaged in a TO-247-3 (TO-247AC) through-hole package.
The operating junction temperature range is -55°C to 150°C.
The maximum peak one-cycle non-repetitive surge current is 3500 A (per leg) for a 5 μs sine wave.
The maximum junction capacitance per leg is 1850 pF, measured at VR = 5 V and 100 kHz to 1 MHz.
