12CWQ03FN Description

Short technical summary and product information.

The 12CWQ03FN is a Schottky rectifier diode array featuring a common cathode configuration with two diodes per package. It is rated for a peak repetitive reverse voltage of 30V and an average rectified forward current of 6A per leg (12A total). The device offers low forward voltage drop: 0.43V typical at 6A and 25°C, and 0.33V typical at 125°C. It has a maximum forward voltage of 0.47V at 6A and 25°C.

 

This diode array is suitable for high-frequency switching applications such as switching power supplies, converters, and free-wheeling diodes. It features guard ring construction for enhanced ruggedness and long-term reliability. The device is housed in a surface mount DPAK (TO-252) package, which provides a small footprint for space-constrained designs.

 

The junction temperature range is -55°C to 150°C, and the thermal resistance from junction to case is 4.7°C/W per leg. The part is Pb-free and RoHS compliant according to the datasheet. It is available in tape and reel packaging with 2500 pieces per reel.
