It uses a phototransistor with a base connection for the output, giving you the option to bias the base for faster switching or lower leakage — handy when you need to tune the response in a motor drive or industrial PLC input. Turn-on time of 220ns and turn-off of 350ns are quick for a phototransistor opto. That matters if you are isolating a digital signal like an encoder pulse train or a PWM gate drive — you get clean edges without adding a Schmitt trigger on the output. The minimum current transfer ratio of 15% at 16mA forward current means you need to budget enough LED drive to guarantee the output transistor saturates over the full temperature range. At 8mA output per channel, this part handles standard logic loads like a microcontroller input or a relay driver directly. ## Package and mounting — what to expect on the board The gull wing leads are visible for inspection, which is a plus for rework in the field — you can see the solder joint. The 8-SMD footprint is common across the NEPOC family, so swapping between single-channel variants in layout is straightforward if the BOM changes. ## Lifecycle and supply posture No official successor or second-source cross is recorded in the NEPOC line for this specific order code, but the PS2801C-4-V-A is a four-channel sibling with similar isolation and transistor output — useful if you need channel density and can accept a 2500Vrms isolation rating instead of 5000Vrms.","metaTitle":"PS8501L3-AX NEPOC Optocoupler, 5000Vrms Isolation, 8-SMD","metaDescription":"PS8501L3-AX NEPOC single-channel optocoupler with 5000Vrms isolation, transistor with base output, 220ns/350ns switching, -55°C to 100°C.

With a forward voltage of 1.7V typical and a maximum output voltage of 35V, the input side works with 3.3V logic through a series resistor.
