4N33 Description

Short technical summary and product information.

The Vishay Dale 4N33 is an optically coupled isolator designed for high isolation applications. It utilizes a gallium arsenide infrared LED paired with a silicon photodarlington sensor to achieve a high degree of isolation between driving and load circuits.

 

Key electrical specifications include a 5300Vrms isolation voltage and a minimum current transfer ratio (CTR) of 500% at 10mA. The device operates with a forward current of up to 60mA and features a typical Vce saturation of 1V. The output type is Darlington with base connection, and it offers a turn-on time of 5µs and a turn-off time of 100µs.

 

This optocoupler is housed in a standard 6-DIP package with a 0.300" (7.62mm) lead spacing, designed for through-hole mounting. It operates within a temperature range of -55°C to 100°C.

 

The 4N33 can be used as a replacement for reed and mercury relays, offering advantages such as long life and high-speed switching. It is suitable for applications requiring reliable signal isolation.
