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:

• 4-pin DIP package
• Double transfer mold package (Ideal for Flow Soldering)
• Current transfer ratio (CTR : MIN. 50% at IF=5 mA, VCE=5V)
• Several CTR ranks available
• Reinforced insulation type (Isolation distance : MIN. 0.4mm)
• Long creepage distance type (wide lead-form type only : MIN. 8mm)
• High isolation voltage between input and output (Viso(rms) : 5.0 kV)

Package: PDIP-4
