DBR72405TU is a UL approved normally closed high voltage reed relay from the DB(UL) series, designed for applications requiring high isolation voltages. This relay features 5kV isolation across contacts, rhodium contact material for low contact resistance (50 mO max, 15 mO typical), and a 24VDC coil with 925O resistance. It offers a maximum switching power of 50W, switching voltage of 1000V DC/AC peak, and switching current of 3A DC/AC peak. The relay provides 17kV contact-to-coil isolation and operates over a temperature range of -20°C to +70°C. Common applications include cardiac defibrillators, test equipment, and high voltage power supplies where high reliability and excellent isolation are required.
