Sensata Technologies Reed Relays DBT71275FU

The DBT71275FU is a normally closed, high-voltage reed relay with 7.5 kV isolation, featuring tungsten contacts for switching up to 5000 V DC/AC peak and 2 A DC/AC peak, with a 3 A carry current. It has a 12 V DC coil (240 Ω), operate voltage of 9 V DC, and release voltage of 1.25 V DC. The relay supports PCB mount with flying lead HV connections and is UL approved for pollution degree 2. Dimensions are 50.8 mm between mounting hole centers with two M4 clearance holes. Operating temperature ranges from -20 °C to +70 °C. Contact capacitance is less than 0.2 pF, insulation resistance exceeds 10¹⁰ Ω, and contact resistance is 250 mΩ max (typical 100 mΩ). Lifetime is 10⁶ operations at 50 W switching power.
