2. Cautions regarding noise

Be aware that when voltage is applied suddenly between the photocoupler’s input and output at startup, the output

transistor may enter the on state, even if the voltage is within the absolute maximum ratings.

USAGE CAUTIONS

1. This product is weak for static electricity by designed with high-speed integrated circuit so protect against static

electricity when handling.

2. Board designing

(1) By-pass capacitor of more than 0.1

between the leads of the photocoupler and capacitor is no more than 10 mm.

(2) In older to avoid malfunctions and characteristics degradation, IGBT collector or emitter traces should not be

closed to the LED input.

3. Make sure the rise/fall time of the forward current is 0.5

μs or less.

4. In order to avoid malfunctions, make sure the rise/fall slope of the supply voltage is 3 V/

μs or less.

5. Avoid storage at a high temperature and high humidity.
