Sensata Technologies Reed Relays DBT70575U

The DBT70575U is a normally closed, high-voltage reed relay with 7.5 kV isolation between contacts, designed for applications requiring high reliability such as cardiac defibrillators and test equipment. It uses a tungsten contact material capable of switching up to 5000 V DC/AC peak and carries a maximum current of 2 A. The relay is PCB-mountable with flying lead high-voltage connections and a 5 V DC coil. It features a contact resistance of 250 mΩ (typical 100 mΩ), insulation resistance exceeding 10¹⁰ Ω, and operates within a temperature range of -20°C to +70°C. The part is UL approved for pollution degree 2 and measures 50.8 mm between mounting hole centers with M4 clearance holes of 4.8 mm to 5.1 mm diameter.
