What about the TOCON scatter?

A TOCON is a sophisticated product where a lot of different components create the TOCONs function. All of these components properties, e.g. the efficiency of the UV-sensing SiC chip or the gain resistors value scatter within a certain range. This results in the TOCONs total scatter of +-20%. per class and the availability of a number of classes for each TOCON type. This means, if you buy a certain quantity of TOCONs it could happen that one TOCON e.g. outputs a voltage of 1000 mV at a certain radiation. The less sensitive TOCON within the batch may output 1000 mV minus 20% = 800 mV and the most sensitive TOCON may output 1200 mV. In most cases the scatter does not cause problems if suited analogue or digital output voltage analysing components are used. However, one very important point needs to be considered: The TOCON must never saturate while illuminated with UV radiation. Saturation means that the TOCON's output voltage Vout equals to the power supply voltage Vin. Saturation will not damage the TOCON but means the output voltage is no longer proportional to the radiation to be measured. This information is quite important for developers who purchase a certain sample quantity or just one TOCON and consider to order a volume quantity. To make sure that not a single TOCON of this volume quantity will saturate in use you should make sure that the sample(s) do not output a voltage higher than 50% of the input voltage while illuminated with the maximum radiation to be measured (e.g. the radiation of a new lamp). If Vout is higher than half of Vin one may try to increase the distance to the UV source or to purchase a less sensitive TOCON (see table below). This +-20% scatter per class is a default value, and you should prepare your surrounding circuitry to handle TOCONs of several classes. If this causes problems, please contact us. By means of binning processes we feel able to reduce the scatter of the batch. However, please consider that also a reduced scatter still requires an individual calibration of each TOCON. Thus, usually scatter reduction does not create a technical benefit.

What is the output pin impedance (or the drive capability) of the TOCON sensor?
