The 4-DIP through-hole package keeps creepage distance consistent with the isolation rating, so no additional slotting is needed on a 2-layer board. ## CTR spread and drive margin Current transfer ratio spans 50% min to 600% max at 5mA forward current. That spread means the designer must verify the downstream logic threshold is met at the minimum CTR across temperature. For a 5mA LED drive, the output transistor can sink up to 50mA — enough to drive a relay coil or a logic gate input directly. Operating from -55°C to 110°C covers outdoor telecom cabinets and industrial enclosures without derating. Typical rise/fall times of 4µs and 3µs limit this part to low-frequency switching — think 50/60Hz line sync or DC-level sensing, not high-speed data isolation. The FOD817300 is a standard through-hole DIP — no MSL concerns, no moisture bake needed before assembly. Confirm the mating pin spacing (0.300\" row-to-row) matches your PCB layout before committing.","metaTitle":"FOD817300 onsemi Optoisolator 5000Vrms Transistor Output","metaDescription":"FOD817300 onsemi optoisolator, 5000Vrms isolation, transistor output, 50-600% CTR at 5mA, -55°C to 110°C, 4-DIP through hole.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Mfr":"onsemi","Series":"-","Package":"Box","Input Type":"DC","Output Type":"Transistor","Mounting Type":"Through Hole","Package / Case":"4-DIP (0.300\\\", 7.62mm)","Product Status":"Active","lifecycle_stage":"eol_hot","Number of Channels":"1","Base Product Number":"FOD817","Voltage - Isolation":"5000Vrms","Vce Saturation (Max)":"200mV","Operating Temperature":"-55°C~110°C","Rise / Fall Time (Typ)":"4µs, 3µs","Voltage - Output (Max)":"70V","Supplier Device Package":"4-DIP","Current - Output / Channel":"50mA","Current Transfer Ratio (Max)":"600% @ 5mA","Current Transfer Ratio (Min)":"50% @ 5mA","Voltage - Forward (Vf) (Typ)":"1.2V","Turn On / Turn Off Time (Typ)":"-","Current - DC Forward (If) (Max)":"50 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5500","priceTiers":[{"qty":1,"price":"$0.55000","currency":"USD"},{"qty":10,"price":"$0.35900","currency":"USD"},{"qty":100,"price":"$0.23760","currency":"USD"},{"qty":1000,"price":"$0.18342","currency":"USD"},{"qty":2000,"price":"$0.16574","currency":"USD"},{"qty":5000,"price":"$0.15469","currency":"USD"},{"qty":10000,"price":"$0.14917","currency":"USD"},{"qty":25000,"price":"$0.14696","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/97f795ec3476128abe24ed3f2e223d6c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/FOD817300/alternatives.json"},"ai":{"faq":[{"question":"What is the Vce saturation of FOD817300?","answer":"200mV maximum.
