10 kV Electrical Rating.
High Current Transfer Ratio.
Low Cost Plastic Module.
Designed for VDE and British Standards.
Designed For UL Recognition (note 6).
The IS1264 Series each consist of a Gallium Arsenide near infrared light
emitting diode, coupled to an NPN silicon phototransistor sealed in an epoxy
housing.
All electrical parameters are 100% tested.
Designed for applications requiring high voltage isolation between input and output.

1. Measured with input diode leads shorted together and output leads shorted
together .
2. RMA flux is recommended. Duration can be extended to 10s max
when flow soldering.
3. Derate linearly 0.73mA/°C above 25°C.
4. Derate linearly
0.91mW/°C above 25°C.
5. Derate linearly 1.82mW/°C above 25°C.
6.
UL recognition is for 3500V AC, 1 minute, only.
