DAT71275FU 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 7.5 kV isolation rating across contacts with rhodium contact material, delivering low contact resistance of 50 mO (typical 15 mO) and excellent insulation resistance of 10¹° O minimum. The relay supports a maximum switching power of 50 W, maximum switching voltage of 1000 V DC or AC peak, and maximum switching current of 3 A, with a carry current capacity of 4 A. It is configured for PCB mounting with flying lead HV connection using UL3239 22 AWG cable rated for 20 kV, and operates over a temperature range of -20°C to +70°C. The DAT71275FU is ideal for high-voltage applications such as cardiac defibrillators, test equipment, and high-voltage power supplies where reliable switching and high isolation are critical.
