With a current transfer ratio (CTR) specified at 80% minimum and 160% maximum when the forward diode is driven at 5 mA, the part provides enough gain headroom to drive logic inputs or low-power loads without an external buffer — but the 80% floor at 5 mA is the number to design to for worst-case margin. ## Switching speed and temperature range Typical turn-on and turn-off times are 3 µs each, with rise and fall times of 2 µs and 3 µs respectively — fast enough for 100 kHz isolated communication or PWM feedback, but not for high-speed digital isolation above 1 Mbps. ## Package and mounting details The 4-SOP footprint is compatible with standard SOIC-4 land patterns; no special pad geometry is required beyond the datasheet recommendation. ## Lifecycle and compliance The device is ROHS3 compliant, meeting the latest EU restriction-of-hazardous-substances directive without exemption.","metaTitle":"FODM217A Optoisolator, 3750Vrms, Transistor Output","metaDescription":"onsemi FODM217A single-channel transistor-output optoisolator, 3750Vrms isolation, 80%–160% CTR at 5 mA, –55°C to 110°C, 4-SOP package.","metaKeywords":null},"attributes":{"series":"FODM217","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Series":"FODM217","Package":"Tube","Input Type":"DC","Output Type":"Transistor","Mounting Type":"Surface Mount","Package / Case":"4-SOIC (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Number of Channels":"1","Voltage - Isolation":"3750Vrms","Vce Saturation (Max)":"400mV","Operating Temperature":"-55°C ~ 110°C","Rise / Fall Time (Typ)":"2µs, 3µs","Voltage - Output (Max)":"80V","Supplier Device Package":"4-SOP","Current - Output / Channel":"50mA","Current Transfer Ratio (Max)":"160% @ 5mA","Current Transfer Ratio (Min)":"80% @ 5mA","Voltage - Forward (Vf) (Typ)":"1.2V","Turn On / Turn Off Time (Typ)":"3µs, 3µs","Current - DC Forward (If) (Max)":"50 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.70000","currency":"USD"},{"qty":10,"price":"$0.45800","currency":"USD"},{"qty":100,"price":"$0.30290","currency":"USD"},{"qty":1000,"price":"$0.23389","currency":"USD"},{"qty":2000,"price":"$0.21134","currency":"USD"},{"qty":5000,"price":"$0.19725","currency":"USD"},{"qty":10000,"price":"$0.19021","currency":"USD"},{"qty":25000,"price":"$0.18739","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2a1a955f5e4901578188c509b39f9c66.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between FODM217A and the base FODM217?","answer":"The FODM217A is a specific CTR-binned variant within the FODM217 series.
