It gives you 2500Vrms isolation between input and output sides, with each channel able to sink 60mA and switch up to 350V on the output. The Darlington pair per channel means the current transfer ratio runs from 400% minimum to 4500% maximum at 1mA forward current — so a tiny LED drive current on the input can switch a much larger load on the output side. This is the part you reach for when you need to isolate PLC digital inputs, drive small relays or solenoids from a microcontroller, or level-shift across a safety barrier in industrial controls. ## What the 2500Vrms and 350V ratings mean for your isolation barrier The 2500Vrms isolation voltage is the basic safety isolation rating — it passes the hipot test for reinforced insulation in many industrial and appliance designs. On the output side, the 350V collector-emitter rating means this Darlington can switch loads like 24V DC relays, 48V telecom rails, or 120V AC signals through an external rectifier, all while keeping the low-voltage logic side electrically isolated. The 60mA per-channel continuous current handles most small electromechanical loads directly; for higher current, use the Darlington output to drive a power MOSFET or larger relay coil. With a minimum CTR of 400% at 1mA forward current, you can drive the input LED with as little as 1mA from a GPIO pin and still get enough photo-current to saturate the Darlington output. The 4500% maximum means the gain is high — good for driving logic inputs or low-current loads, but if you are switching a relay coil, you might want a series base resistor on the output side to limit saturation current and keep switching speed predictable. The 20µs rise and 5µs fall times are typical for a Darlington optocoupler; not for high-speed data, but fine for 10kHz-ish switching or DC level sensing. ## Temperature range and where this part lives comfortably Rated for -55°C to 100°C operating temperature, this optocoupler handles cold-start in unheated equipment enclosures and the warmth inside a crowded control cabinet. The 100°C upper limit is the ambient — derate the 60mA output current if the board runs hot. ## Active lifecycle and compliance — no LTB worry The NEPOC series is Renesas's optocoupler family, and this variant has been around long enough to have established second-source equivalents in the market. ## Sourcing this part — what to expect For volume requirements or urgent BOM fills, send an RFQ; the multi-source reach of independent distribution covers this NEPOC line.","metaTitle":"PS2833-4-F3-A NEPOC 4-Ch Darlington Optocoupler, 2500Vrms","metaDescription":"PS2833-4-F3-A NEPOC 4-channel Darlington optocoupler with 2500Vrms isolation, 400%-4500% CTR at 1mA, 60mA output per channel, 350V output max.","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":"16-SOIC (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Number of Channels":"4","Voltage - Isolation":"2500Vrms","Vce Saturation (Max)":"1V","Operating Temperature":"-55°C ~ 100°C","Rise / Fall Time (Typ)":"20µs, 5µs","Voltage - Output (Max)":"350V","Supplier Device Package":"16-SSOP","Current - Output / Channel":"60mA","Current Transfer Ratio (Max)":"4500% @ 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":"$5.46","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.46000","currency":"USD"},{"qty":10,"price":"$3.86000","currency":"USD"},{"qty":100,"price":"$3.16170","currency":"USD"},{"qty":500,"price":"$2.66540","currency":"USD"},{"qty":1000,"price":"$2.44481","currency":"USD"},{"qty":2500,"price":"$2.34370","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7044a77f639c6bcf439344ccad0d7889.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How many channels does PS2833-4-F3-A have and what is the output type?","answer":"It has 4 channels with Darlington output, each rated for 60mA continuous current and 350V maximum output voltage."},{"question":"Is PS2833-4-F3-A a direct replacement for PS2833-4?","answer":"The PS2833-4-F3-A is a specific ordering variant within the PS2833-4 family.
