Trip Time
Note 1
For operation in ambient temperatures above 25 C the device must be derated based on a 125 C maximum junction temperature and a thermal resistance
of 80 CW junction to ambient for the DIP and 162 CW for the SO Package
Note 2
Average of 10 trials
Note 3
Required UL sensitivity tolerance is such that external trimming of LM1851 sensitivity will be necessary
Note 4
This externally applied current is in addition to the internal ‘‘output drive current’’ source
