CEFC304-G Description

Short technical summary and product information.

The CEFC304-G is a fast recovery rectifier diode from Comchip Technology, designed for high-efficiency applications requiring fast switching. It has a maximum repetitive reverse voltage of 400V and an average forward current rating of 3A.

 

Key electrical characteristics include a maximum forward voltage of 1.3V at 3A, a reverse recovery time of 50ns, and a peak forward surge current of 100A (8.3ms single half sine-wave). The diode exhibits a low reverse leakage current of 10µA at 25°C and 200µA at 100°C, with a typical junction capacitance of 55pF.

 

The device is housed in a surface mount DO-214AB (SMC) package, suitable for automated assembly. It has a maximum junction-to-lead thermal resistance of 10°C/W and can operate at junction temperatures up to 150°C. Storage temperature range is -55°C to +150°C.

 

Environmental compliance includes RoHS3 compliance, REACH unaffected status, and UL 94V-0 flammability rating for the plastic package. The moisture sensitivity level is MSL 1 (unlimited), allowing flexible handling during assembly.
