DBT70505PU is a UL approved normally closed high voltage reed relay featuring 5kV isolation across contacts and tungsten contact material. It operates with a 5V DC coil (must operate voltage 3.7V DC, coil resistance 38O) and offers a maximum switching voltage of 3500V DC/AC peak with switching power up to 50W. The relay provides panel mount configuration with wire wrap terminals and features 17kV contact-to-coil isolation. With an operating temperature range of -20°C to +70°C and capacitance across contacts of less than 0.2pF, this relay is suitable for high reliability applications such as cardiac defibrillators, test equipment, and high voltage power supplies.
