DBT70575U is a UL-approved normally closed high voltage reed relay designed for applications requiring very high isolation voltages. It features 7.5kV isolation across contacts with tungsten contact material, enabling switching voltages up to 5000V DC/AC peak. The relay operates with a 5V DC coil (must operate voltage 3.7V, must release voltage 0.5V) with a coil resistance of 38O, and offers fast switching with 2.0ms operate time and 3.0ms release time. With a maximum switching power of 50W, switching current of 2A, and carry current of 3A, this relay provides reliable performance across an operating temperature range of -20°C to +70°C. Common applications include cardiac defibrillators, test equipment, and high voltage power supplies where high reliability and isolation are critical.
