Description
The 4N25 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 20% at input current of 10 mA.
Applications
• I/O interfaces for computers
• System appliances, measuring instruments
• Signal transmission between circuits of different potentials and impedances
Features
• Response time (tr: typ., 3 µs at VCE = 10 V, IC = 2 mA, RL = 100 Ω)
• Current Transfer Ratio (CTR: min. 20% at IF = 10 mA, VCE = 10 V)
• Input-output isolation voltage (Viso = 2500 Vrms)
• Dual-in-line package
