The 4N25-000E is an optocoupler for general purpose photocoupler 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 us and minimum CTR is 20% at input current of 10 mA. ### Features
The 4N35-000E is an optocoupler for general purpose photocoupler 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 us and minimum CTR is 100% at input current of 10 mA. ### Features
The 4N25 is an industry standard single channel Phototransistor Coupler with base connection. The optocoupler consists of gallium arsenide infrared LED and a silicon NPN phototransistor.
