The 3750Vrms isolation rating suits it for breaking ground loops in industrial digital interfaces like CAN, RS-485, and SPI lines where the signal rate exceeds what a standard photocoupler can pass. ## Active production, tube delivery The 8-SOIC package is a standard footprint shared by many logic optoisolators, so the board layout is straightforward. ## Supply rail and temperature range The part operates from a 4.5V to 5.5V supply on both sides — it is a 5V-logic part, not 3.3V-compatible without a level shifter. The industrial temperature range of -40°C to 100°C covers most factory-floor and outdoor telecom enclosures without forced cooling. Rise and fall times are 5ns and 4.5ns typical, which keeps the output edges clean for driving CMOS or TTL inputs directly.","metaTitle":"FOD0720 onsemi Optoisolator – 25Mbps, 3750Vrms","metaDescription":"onsemi FOD0720 optoisolator: 25Mbps data rate, 3750Vrms isolation, push-pull output in 8-SOIC.

For 3.3V systems, you would need a level translator between the 3.3V logic and the FOD0720 input, or look at a 3.3V-rated optoisolator such as the FOD8001R2 which also runs at 25Mbps but has a wider supply range."},{"question":"Does the FOD0720 require an external pull-up resistor on the output?","answer":"No — the output is push-pull, totem pole, which means it actively drives high and low. Unlike open-collector optoisolators, you do not need a pull-up resistor on the output side, saving one component per channel."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/FOD0720","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/FOD0720 when reusing this data.
