4N37M Description

Short technical summary and product information.

The ON Semiconductor 4N37M is a general-purpose optocoupler designed for reliable signal isolation. It consists of a gallium arsenide infrared emitting diode driving a silicon phototransistor within a standard 6-pin dual-in-line package.

 

This optocoupler provides a high isolation voltage of 4170Vrms, making it suitable for applications requiring separation between circuits. It operates with a forward current of 60 mA and offers a minimum Current Transfer Ratio (CTR) of 100% at 10 mA.

 

The 4N37M is designed for through-hole mounting and comes in a 6-DIP package. It operates within a temperature range of -40°C to 100°C. Key electrical characteristics include a maximum collector emitter saturation voltage of 300mV and a maximum collector emitter voltage of 30V.

 

Applications for this optocoupler include power supply regulators, digital logic inputs, and microprocessor inputs where electrical isolation is critical.
