DAT72415F-HR is a high-voltage reed relay designed for demanding applications requiring exceptional isolation and reliability. This 15 kV SPNO (normally open) relay features tungsten contacts with flying lead connections and high insulation resistance (1×106 O minimum), making it ideal for sensitive test and measurement circuits with minimal leakage current losses. The relay operates with coil voltages of 5V, 12V, or 24V DC, with a maximum switching voltage of 10,000 V DC or AC peak and a maximum switching current of 2 A. It delivers a maximum switching power of 50 W and maintains a contact resistance of 250 mO (typical 100 mO), with an operating temperature range of -20°C to +70°C. The tungsten contact construction enables switching of higher voltages compared to rhodium alternatives, making this relay particularly suitable for cardiac defibrillators, high-voltage power supplies, and precision test equipment where high isolation and reliability are critical.
