Its headline feature is the current transfer ratio: 400% minimum, 4500% maximum, both specified at a forward current of 1 mA. That means a 1 mA LED current can switch a 60 mA output load — the Darlington gain lets you drive the input directly from a GPIO without a transistor buffer, which simplifies the BOM on industrial I/O cards and PLC modules. ## 2500Vrms isolation — where it fits With 2500Vrms of galvanic isolation, this part is sized for reinforced insulation in mains-connected equipment: switch-mode power supply feedback loops, motor-drive interface circuits, and industrial sensor isolation. The output side can handle up to 350V and 60 mA continuously, so it can switch a 24V PLC input or a 240V AC relay coil through an external transistor. Rise and fall times are 20 µs and 5 µs respectively — fast enough for 10 kHz switching but not for high-speed data; this is a level-shifter and isolator, not a digital coupler. ## Temperature range: -55°C to 100°C The Darlington output's Vce saturation is 1V max, which is higher than a transistor-output opto — budget that drop when calculating the load voltage margin at cold start.","metaTitle":"PS2933-1-V-F3-AX NEPOC Optocoupler","metaDescription":"Renesas PS2933-1-V-F3-AX NEPOC single-channel Darlington optocoupler, 2500Vrms isolation, 400%-4500% CTR at 1mA, 350V output, -55°C to 100°C.

The PC817 is a transistor-output optocoupler with a typical CTR around 50–600%, while the PS2933-1-V-F3-AX uses a Darlington output with 400%–4500% CTR at 1 mA. The Darlington's higher gain lets you drive the input with much less current, but its Vce saturation is 1V versus ~300 mV for a transistor output. If your circuit needs the low saturation voltage, the PS2801C-4-V-A (transistor output, 4-channel) is a closer functional match — though it is a 4-channel device in a different package, not a single-channel drop-in."},{"question":"Is PS2933-1-V-F3-AX RoHS compliant?","answer":"Yes, it is ROHS3 compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/PS2933-1-V-F3-AX","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/PS2933-1-V-F3-AX when reusing this data.
