The DAT71210F-HR is a high-voltage reed relay designed for demanding applications requiring exceptional isolation and low leakage current. This 10 kV isolation relay features flying lead HV connections with UL3239 22 AWG cable rated for 20 kV, and incorporates a high vacuum reed switch with rhodium or tungsten contacts to achieve superior performance. The relay operates with coil voltages of 5V, 12V, or 24V DC, with a must-operate voltage of 3.7–20V DC and a must-release voltage of 0.5–4V DC, while maintaining an insulation resistance of 1×10¹4 O minimum. With a maximum switching voltage of 5000V DC/AC peak, maximum switching current of 2A, and maximum carry current of 3A, the relay is ideal for sensitive test and measurement circuits, cardiac defibrillators, and high-voltage power supplies where low contact resistance and high reliability are essential.
