The slower the rise time of the input voltage the greater the maximum value of the additional external capacitance for reliable start up.

The devices are fully compatible with CECC00802 to 280°C which allows them to be placed and reflowed with IC’s, thus reducing time and cost in production. The co-planarity of the pin positions is based upon IEC 191-6:1990. The devices are suitable for all applications where high volume production is envisaged.
