In photovoltaic mode. Maximum linear current specifies the level at which the output current characteristic deviates more than 10% from the
straight line. The short circuit current saturates at approximately 10 times this level.
Response Time (transition time between 10% and 90% of the output signal amplitude) measured at 670 nm with a 50Ω load. Shorter wavelengths
will result in faster rise and fall times.
Storage and Operating Temperature Range for all photodiodes is -40°C to 110°C, except for the SD 225-23-21-040, which is –25°C to 100°C.
