Description
The 4N35 is an optocoupler for general purpose applications. It contains a light emitting diode optically coupled to a photo-transistor. It is packaged in a 6-pin DIP package and available in wide-lead spacing option and lead bend SMD option. Response time, tr, is typically 3 µs and minimum CTR is 100% at input current of 10 mA.

Features
• High Current Transfer Ratio
   (CTR: min. 100% at IF = 10 mA, VCE = 10 V)
• Response time
   (tr: typ., 3 µs at VCE = 10 V, IC = 2 mA, RL = 100 Ω)
• Input-output isolation voltage
   (Viso = 3550 Vrms)
• Dual-in-line package
• UL approved
• CSA approved
• IEC/EN/DIN EN 60747-5-2 approved
• Options available:         
   – Leads with 0.4" (10.16 mm) spacing (W00)
   – Leads bends for surface mounting (300)
   – Tape and reel for SMD (500)       
   – IEC/EN/DIN EN 60747-5-2 approvals (060)

Applications
• I/O interfaces for computers
• System appliances, measuring instruments
• Signal transmission between circuits of different
   potentials and impedances
