Product Description
CT354 AC Input 4-Pin Mini-Flat Phototransistor Optocoupler
Product Overview
The CT354 series is an AC input optocoupler featuring a phototransistor optically coupled to two gallium arsenide infrared-emitting diodes, housed in a 4-lead Mini-Flat package. It offers high isolation of 3750 VRMS and operates within a temperature range of -55 C to 110 C. This optocoupler is suitable for applications in switch mode power supplies, computer peripheral interfaces, and microprocessor system interfaces. CTR flexibility is available as per order information.
