Dielectric strength between I/O (See note 1.) (See note 2.) VI-O 500 Vrms AC for 1 min
Ambient operating temperature Ta -40 to +110 ºC With no icing or condensation
Ambient storage temperature Tstg -40 to +125 ºC With no icing or condensation
Soldering temperature 260 ºC 10 s
Note: 1. The dielectric strength between the input and output was checked by applying voltage between all pins as a group on the LED side and all pins as a group on the light-receiving side.
  2. Dielectric strength between I/O 500Vrms is applied from production in December 2016. (Before changes are 300Vrms.)
