* All specifications are per element. All values at 23°C
1. Dark Current and Shunt Resistance vary with temperature as follows; for T≠23°C, IDT = ID23 * 1.09∆T,
RSHT= RSH23 * 0.9∆T, where ∆T=(T-23) and ID23 and RSH23 are values at 23°C.
2. Typical values listed. Minimum value shall be 50% of typical.
3. Typical values listed. Maximum value shall be 20% higher than the typical.
4. Test conditions are VB = 10mV, and 632.8 nm.
5. Test conditions are VB = 10mV, and 950 nm.
6. 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.
7. 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.
