DAR70575FU is a UL-approved, normally open high-voltage relay from the DA(UL) series designed for high-reliability applications requiring high isolation voltages. This relay features 7.5 kV isolation across contacts with rhodium contact material, providing low contact resistance of 50 mO (typical 15 mO) and excellent insulation resistance of 10¹° O. The relay operates with a 5V DC coil, requiring a must-operate voltage of 3.7V and must-release voltage of 0.5V, with operate and release times of 3.0 ms and 2.0 ms respectively when a diode is fitted. It supports a maximum switching voltage of 1000V DC/AC peak and maximum switching current of 3A, with a maximum carry current of 4A and switching power of 50W. The flying lead connection variant with PCB mounting makes it suitable for cardiac defibrillators, test equipment, and high-voltage power supplies where compact integration and reliable high-voltage isolation are essential.
