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