The DAT70505TU is a UL-approved, normally open high-voltage relay from the DA(UL) series featuring 5kV isolation voltage achieved through high vacuum reed switches with rhodium or tungsten contacts. This relay is engineered for high-reliability applications such as cardiac defibrillators, test equipment, and high-voltage power supplies, with switching capabilities up to 3A DC/AC peak current and 1000V DC or 3500V AC peak switching voltage for rhodium contacts. The relay offers low contact resistance (50 mO typical for rhodium contacts), excellent AC characteristics, and multiple connection options including flying leads, solder turret (wire wrap), and 1/4" spade terminals. Operating over a temperature range of -20°C to +70°C with a coil voltage of 5V DC, the DAT70505TU provides robust isolation across contacts and is ideal for applications requiring high voltage switching with minimal signal distortion.
