The DBT71210F-HR is a high-voltage reed relay designed for demanding applications requiring exceptional isolation and low leakage current. This 10 kV isolation relay features tungsten contacts with flying lead connections (UL3239, 22 AWG, 20 kV rated cable), making it suitable for sensitive test and measurement circuits. The relay achieves a minimum insulation resistance of 1×10¹4 Ohms and operates with coil voltages of 5V, 12V, or 24V DC, with must-operate voltage of 3.7–9 V DC and must-release voltage of 0.5–1.25 V DC. Key electrical characteristics include a maximum switching voltage of 5000 V DC or AC peak, maximum switching current of 2 A, and maximum carry current of 3 A, with a contact resistance of 250 mO (typical 100 mO). The relay operates reliably over a temperature range of -20°C to +70°C and is ideal for high-reliability applications such as cardiac defibrillators, test equipment, and high-voltage power supplies.
