ACST Varistor Diodes are optimised for operation under forward bias conditions. They feature low series resistance and exponential behaviour of forward I-V characteristics, which extends over up to 8 orders of magnitude of the forward current. This allows for high linearity and high dynamic range MM/SubMM-Wave mixers, which are important for many applications like are radiometry and measurement instrumentation.

Due to particular material system and fabrication technology, these diodes survive temperatures up to 250°C for short time, which may be required i.e. for soldering into surrounding circuitry.
