AKM CZ375DCB-HA

The CZ-375D is an open-loop current sensor utilizing a Hall sensor that outputs an analog voltage proportional to AC/DC current. The Hall sensor employs a III-V compound semiconductor thin film, enabling high-accuracy, high-speed current detection. The coreless ultra-compact SMT package saves board space. In addition, the low primary conductor resistance suppresses heat generation, achieving continuous current of 100A RMS. Conventional coreless current sensors suffer from accuracy degradation due to stray magnetic field interference. The CZ-375x series features a built-in stray magnetic field rejection function to suppress this effect. The CZ-375x series also complies with the UL 61800-5-1 safety standard, making it well-suited for applications such as industrial EV charging stations and commercial air conditioning systems. While sharing the same package as the CZ-370x series, the CZ-375x series supports a wide current detection range, from ±115A peak (CZ-375A) to ±225A peak (CZ-375D). This allows designers to use the same PCB layout across different products and helps users scale their designs across various current rating options.
