It provides 5000Vrms of galvanic isolation between input and output, making it suitable for industrial power supplies, motor drives, PLC I/O modules, and any application where a clean isolation barrier is needed between a low-voltage control side and a higher-voltage load side. ## 200% to 400% CTR at 5 mA — design margin for aging and temperature The current transfer ratio (CTR) is specified at 200% minimum and 400% maximum when the LED is driven with 5 mA forward current. The 300mV maximum Vce saturation at 50 mA output current keeps power dissipation low. The NEPOC series is a mature, widely-used optocoupler family with consistent supply. ROHS3 compliance is confirmed, so the part meets current environmental regulations for European and global markets.","metaTitle":"PS2561B-1-L-A NEPOC Optocoupler, 5000Vrms, 4-DIP","metaDescription":"Renesas NEPOC PS2561B-1-L-A single-channel transistor-output optocoupler, 5000Vrms isolation, 200-400% CTR at 5mA, -55°C to 110°C, 4-DIP through-hole.","metaKeywords":null},"attributes":{"series":"NEPOC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Series":"NEPOC","Package":"Tube","Input Type":"DC","Output Type":"Transistor","Mounting Type":"Through Hole","Package / Case":"4-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Number of Channels":"1","Voltage - Isolation":"5000Vrms","Vce Saturation (Max)":"300mV","Operating Temperature":"-55°C ~ 110°C","Rise / Fall Time (Typ)":"3µs, 5µs","Voltage - Output (Max)":"80V","Supplier Device Package":"4-DIP","Current - Output / Channel":"50mA","Current Transfer Ratio (Max)":"400% @ 5mA","Current Transfer Ratio (Min)":"200% @ 5mA","Voltage - Forward (Vf) (Typ)":"1.17V","Current - DC Forward (If) (Max)":"40 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.03","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.08000","currency":"USD"},{"qty":10,"price":"$0.70700","currency":"USD"},{"qty":100,"price":"$0.46320","currency":"USD"},{"qty":1000,"price":"$0.38410","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/eef65ec5db2ed2b60f62ec28ae9a1f18.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/PS2561B-1-L-A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/PS2561B-1-L-A when reusing this data.
