■ Description

PC1231xNSZ0F Series contains an IRED optically coupled to a phototransistor.

It is packaged in a 4-pin DIP, available in wide-lead spacing option and SMT gullwing lead-form option.

Input-output isolation voltage(rms) is 5.0kV.

CTR is 50 to 400 at input current of 0.5mA.

■ Features

1. 4pin DIP package

2. Double transfer mold package (Ideal for Flow Soldering)

3. Low input current type (IF=0.5mA)

4. High resistance to noise due to high common rejection voltage (CMR : MIN. 10kV/s)

5. Reinforced insulation type (Isolation distance : MIN. 0.4mm)

6. Long creepage distance type (wide lead-form type only : MIN. 8mm)

7. High isolation voltage between input and output (Viso(rms) : 5.0kV)

8. RoHS directive compliant

■ Applications

1. Primary to secondary isolation in switch mode power supply

2. Noise suppression in switching circuit

3. Signal transmission between circuits of different potentials and impedances

4. Over voltage detection
