DAT70510FU is a UL-approved, normally open high-voltage relay from the DA(UL) series designed for high-reliability applications requiring very high isolation voltages. This relay features a 5kV isolation rating across contacts with rhodium contact material, delivering low contact resistance of 50 mO (typical 15 mO) and excellent AC characteristics. The relay operates with a 5V DC coil, featuring a must-operate voltage of 3.7V and a must-release voltage of 0.5V, with operate and release times of 3.0 ms and 2.0 ms respectively. It supports a maximum switching power of 50W, maximum switching voltage of 1000V DC or AC peak, and a maximum switching current of 3A, with a carry current capacity of 4A. The flying lead connection option with UL3239 22AWG cable (20kV rated) makes it ideal for cardiac defibrillators, test equipment, and high-voltage power supplies where compact PCB mounting and reliable high-voltage isolation are essential.
