DBT71275PU is a UL-approved normally closed high voltage reed relay designed for applications requiring high isolation voltages. It features tungsten contacts with 7.5kV isolation across contacts (DC or AC peak), a maximum switching voltage of 5000V, and a maximum switching power of 50W. The relay operates with a 12V DC coil (must operate voltage 9V DC, coil resistance 240O) and offers panel mount configuration with wire wrap terminals. With an operating temperature range of -20°C to +70°C, contact to coil isolation of 17kV, 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.
