It provides 5000Vrms galvanic isolation between a DC-input LED and a high-voltage Darlington phototransistor output, making it a fit for motor drives, PLC I/O modules, relay drivers, and AC-line sensing where you need to switch a 350V rail from a logic-level signal. The Darlington configuration delivers a current transfer ratio (CTR) of 400% minimum to 5500% maximum at 1 mA forward current, so a 1 mA LED drive can switch up to 55 mA on the output side. That gain margin lets you drive the LED directly from a 3.3V or 5V GPIO without a buffer transistor, saving board space and BOM cost. ## 350V output and 120 mA per channel — sizing the load The output transistor is rated for 350V collector-emitter and 120 mA continuous current per channel. That combination covers 24VAC/DC industrial loads, 120VAC relays, and small solenoids directly. The 1V Vce(saturation) at 120 mA means about 120 mW dissipation in the output device — fine for the 4-SMD package in still air, but if you're switching near the current limit at high duty cycles, check the thermal derating against the -55°C to 100°C operating range. Rise and fall times are 18 µs and 5 µs typical, so this part suits low-frequency switching (relays, contactors, valve drivers) rather than high-speed data isolation. For sub-microsecond isolation, you'd step up to a digital isolator or high-speed optocoupler. ## Active lifecycle — no obsolescence pressure The NEPOC series is Renesas's established optocoupler family with broad distribution support. ## Package and rework notes The 4-SMD gull-wing package is a straightforward surface-mount footprint — no hidden leads, no thermal pad. Standard MSL 3 handling applies: bake before reflow if the moisture-barrier bag has been open longer than the floor-life window.","metaTitle":"PS2535L-1-F3-A NEPOC Optocoupler, Darlington Output","metaDescription":"PS2535L-1-F3-A NEPOC optocoupler: single-channel Darlington output, 5000Vrms isolation, 400%-5500% CTR at 1mA, 350V output rating.","metaKeywords":null},"attributes":{"series":"NEPOC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Series":"NEPOC","Package":"Tape & Reel (TR); Cut Tape (CT)","Input Type":"DC","Output Type":"Darlington","Mounting Type":"Surface Mount","Package / Case":"4-SMD, Gull Wing","lifecycle_stage":"eol_hot","Number of Channels":"1","Voltage - Isolation":"5000Vrms","Vce Saturation (Max)":"1V","Operating Temperature":"-55°C ~ 100°C","Rise / Fall Time (Typ)":"18µs, 5µs","Voltage - Output (Max)":"350V","Supplier Device Package":"4-SMD","Current - Output / Channel":"120mA","Current Transfer Ratio (Max)":"5500% @ 1mA","Current Transfer Ratio (Min)":"400% @ 1mA","Voltage - Forward (Vf) (Typ)":"1.2V","Current - DC Forward (If) (Max)":"50 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.88","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.88000","currency":"USD"},{"qty":10,"price":"$1.18700","currency":"USD"},{"qty":100,"price":"$0.87820","currency":"USD"},{"qty":500,"price":"$0.80700","currency":"USD"},{"qty":1000,"price":"$0.66458","currency":"USD"},{"qty":2000,"price":"$0.63135","currency":"USD"},{"qty":6000,"price":"$0.61711","currency":"USD"},{"qty":10000,"price":"$0.60287","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/92a92ff7d220cca50788a9ca2e3bf4d6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the CTR of PS2535L-1-F3-A?","answer":"The current transfer ratio (CTR) is 400% minimum to 5500% maximum, measured at 1 mA forward current.
