4N38 Description

Short technical summary and product information.

The Vishay 4N38 is an industry-standard single-channel optocoupler designed for reliable signal isolation. It comprises a gallium arsenide infrared LED coupled with a silicon NPN phototransistor.

 

Key electrical specifications include an isolation test voltage of 5000 VRMS and an input-output coupling capacitance of less than 0.5 pF. The device supports a forward current of 60 mA, a maximum collector current of 100 mA, and a maximum collector-emitter voltage of 80 V. The typical forward voltage is 1.5 V at 1 mA, with a reverse voltage rating of 6 V and a power dissipation of 70 mW.

 

This optocoupler is suitable for various applications such as AC mains detection, reed relay driving, switch mode power supply feedback, and logic ground isolation. It interfaces with common logic families and provides high frequency noise rejection.

 

The 4N38 is available in a standard dual-in-line 6-pin (DIP-6) package, designed for through-hole mounting. It operates within a temperature range of -55°C to +100°C.
