4N37 Description

Short technical summary and product information.

The 4N37 is an optocoupler integrated circuit that uses an infrared emitting diode to drive a phototransistor. It offers a high input-output isolation voltage, with the 4N35 series rated at 3,550Vrms and the 4N37 series at 1,500Vrms. The response time is typically 3 μs.

 

This component is designed for applications requiring electrical isolation, such as power supply regulators, digital logic inputs, and microprocessor inputs. It features a dual-in-line package (DIP-6) suitable for through-hole mounting.

 

The 4N37 meets safety approval standards including UL, CSA, FIMKO, VDE, BSI, and CQC. It has a creepage distance and clearance distance of greater than 8.0 mm, and an isolation thickness of 0.4 mm minimum.

 

Environmental compliance includes RoHS3 compliance and MSL 1. The operating temperature range is from -55°C to +100°C.
