Sensata Technologies Reed Relays DBT72410F-HR

The D-HR series is a high-voltage reed relay designed for applications requiring up to 15kV isolation, such as cardiac defibrillators and test equipment. The DBT72410F-HR variant features a tungsten contact, 10kV isolation, 24V DC coil, and flying leads with PCB mount compatibility. It operates with a maximum switching voltage of 7000V DC, switching current of 2A, and carry current of 3A, with contact resistance of 250 mΩ maximum (100 mΩ typical). Insulation resistance is 1×10¹² Ω minimum and 1×10¹⁴ Ω typical. The relay has an operate time of 2.0 ms and release time of 3.0 ms with a diode fitted. It is rated for operation from -20°C to +70°C and provides 17kV isolation between coil and contacts. Termination style is flying leads with a high insulation resistance designation.
