The KTY83/84/85 series use the more basic single-sensor arrangement. The simplicity of this arrangement allows the sensors to be produced in the compact SOD68; DO-34 (KTY83/84) and SOD80 (KTY85) packages. In addition to simplicity, another important advantage of the single-sensor device is the potential for operation at temperatures up to 300 °C. The KTY84 makes use of this property, being specifically designed for operation at temperatures up to 300 °C. These sensors are polarity dependent.
