Minimum External Air Gap
(External Clearance)
L(101) 5 mm Measured from input terminals to output terminals,
shortest distance through air.
Minimum External
Tracking (External Creepage)
L(102) 5 mm Measured from input terminals to output terminals,
shortest distance path along body.

** The initial switching threshold is 5mA or less. It is recommended that 6.3mA to 10mA be used for best performance and to permit at least a
20% LED degradation guardband.
