■ Description

PC123 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 5mA.

■ Features

1. 4-pin DIP package

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

3. Current transfer ratio (CTR : MIN. 50 at IF=5 mA, VCE=5V)

4. Several CTR ranks available

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) : 5.0 kV)

■ Applications

1. I/O isolation for MCUs (Micro Controller Units)

2. Noise suppression in switching circuits

3. Signal transmission between circuits of different potentials and impedances

4. Over voltage detection
