This isolation level is enough for basic mains-referenced circuits — think AC line sensing, relay drive, or isolated feedback in a 24 V industrial control loop. ## CTR range and switching speed for logic interfacing Current transfer ratio spans 50% to 250% at a 1 mA forward current — that wide spread means you can design for LED current as low as 1 mA and still guarantee a logic-high at the output, even after LED ageing or across temperature. Typical rise and fall times are 3 µs each, which suits 10–100 kHz switching for PLC inputs or digital isolator replacement. ## AC/DC input, 80 V output rating The input side accepts both AC and DC drive — handy if you are coupling a 50/60 Hz mains signal directly through a resistor. Output transistor is rated for 80 V maximum and 50 mA continuous, so it can drive a 5 V or 3.3 V logic rail through a pull-up resistor without a level shifter. ## Sourcing and lifecycle: active, ROHS3, tape-and-reel ROHS3 compliant, supplied in tape-and-reel or cut-tape options. The 4-SOIC package is a standard footprint — reflow profile matches any lead-free solder process.","metaTitle":"FODM214AR2 Optoisolator – onsemi, 3750Vrms, 4-SOIC, Active","metaDescription":"onsemi FODM214AR2 phototransistor optoisolator: 3750Vrms isolation, CTR 50-250% at 1mA, AC/DC input, 4-SOIC.
