Its current transfer ratio is guaranteed between 200% and 400% at 1mA forward current, which means the output transistor can sink enough current to drive a logic gate input or a low-power relay coil without an additional buffer stage. ## Switching speed and output drive capability Typical rise and fall times are 5µs and 5.5µs respectively, with turn-on and turn-off times both at 6µs typ. This suits the part for low-frequency signal isolation up to about 10 kHz — think PLC digital inputs, status feedback, or isolated 24V logic interfaces. The output can handle up to 75V and 30mA continuous, with a Vce saturation of 400mV max at rated current, keeping conduction losses low. ## Temperature grade and package fit The 4-SOIC package with 4.40mm body width (0.173\") is a common footprint shared with many mini-flat optoisolators, making it a drop-in candidate for existing layouts. onsemi lists the product status as Active, and it is ROHS3 compliant. ## Sourcing and volume availability Available in Tape & Reel (TR) and Cut Tape (CT) packaging options for pick-and-place assembly or prototype runs.","metaTitle":"FODM8801CR2 Optoisolator – onsemi OptoHit™, 3750Vrms","metaDescription":"onsemi FODM8801CR2 single-channel transistor-output optoisolator, 3750Vrms isolation, 200-400% CTR at 1mA, -40°C to 125°C, 4-SOIC package.","metaKeywords":null},"attributes":{"series":"OptoHit™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Series":"OptoHit™","Package":"Tape & Reel (TR); Cut Tape (CT)","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":"-40°C ~ 125°C","Rise / Fall Time (Typ)":"5µs, 5.5µs","Voltage - Output (Max)":"75V","Supplier Device Package":"4-Mini-Flat","Current - Output / Channel":"30mA","Current Transfer Ratio (Max)":"400% @ 1mA","Current Transfer Ratio (Min)":"200% @ 1mA","Voltage - Forward (Vf) (Typ)":"1.35V","Turn On / Turn Off Time (Typ)":"6µs, 6µs","Current - DC Forward (If) (Max)":"20 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.70000","currency":"USD"},{"qty":10,"price":"$1.07300","currency":"USD"},{"qty":100,"price":"$0.79430","currency":"USD"},{"qty":500,"price":"$0.72990","currency":"USD"},{"qty":1000,"price":"$0.60109","currency":"USD"},{"qty":2500,"price":"$0.57104","currency":"USD"},{"qty":5000,"price":"$0.55816","currency":"USD"},{"qty":12500,"price":"$0.54528","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f71585aa4236e0c7772349b32506693a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional equivalent to FODM8801CR2?","answer":"Within the same OptoHit™ series, the FODM8801C and FODM8801BV share identical electrical ratings (3750Vrms, 200-400% CTR, same switching times) but come in Tube packaging rather than Tape & Reel.
