(4) Cautions

• Fluxes

Avoid removing the residual flux with freon-based and chlorine-based cleaning solvent.

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

distance 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) Pins 1, 4 (which is an NC

Unconnected pins should not be used as a bypass for signals or for any other similar purpose because this

may degrade the internal noise environment of the device.

*1 NC: Non-Connection (No Connection)

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

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

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