Sensata Technologies Reed Relays DBR71275FU

The DBR71275FU is a normally closed, high-voltage reed relay with 7.5 kV isolation between contacts, designed for high-reliability applications such as cardiac defibrillators and test equipment. It features tungsten contacts capable of switching up to 5000 V DC/AC peak and 2 A current, with a contact resistance of 250 mΩ (typical 100 mΩ). The relay is PCB mounted with flying lead HV connections and operates on a 12 V DC coil with 240 Ω resistance. Operate and release times are 2.0 ms and 3.0 ms with a diode fitted. Isolation between coil and contacts is 17 kV DC/AC peak. The package measures 50.8 mm between mounting hole centers for M4 studs. It is UL approved for pollution degree 2 and operates from -20 °C to +70 °C.
