CZ-3A02

[CZ-3A02] Clearance/Creepage 8mm CZ-3A02 3.3V Output Accurate Coreless Current Sensor 1. General Description CZ-3A02 is an open-type current sensor using Hall sensors, which outputs the analog voltage proportional to the AC/DC current. Group III-V semiconductor thin film is used as the Hall sensor, which enables the high-accuracy and high-speed current sensing. Coreless ultra-small surface mount package realizes the space-saving. Also, the low primary conductor resistance suppresses heat generation to achieve the 50Arms continuous current. Existing coreless current sensors have an accuracy disadvantage from degradations caused by a disturbed magnetic field. The CZ-3A0x series has a built-in stray magnetic field reduction function to suppress this effect. The CZ-3A0x series also has dual overcurrent detection function. The CZ-3A0x series is UL 61800-5-1 safety compliant, which is an excellent fit for industrial AC drives, servo motors, etc. The CZ-3A0x series is also an excellent fit to input the sensor signal into a 3.3V AD converter. The CZ-3A0x series has a large variety of linear measurement ranges, from ±12.9A (CZ-3A01), to ±129.1A, (CZ-3A07). This enables designers to use the same board design across different current rating products. 2.
