Product details

The PS8501L3-E3-AX: The Renesas NEPOC PS8501L3--AX is a single-channel DC-input optocoupler with a phototransistor output that includes a base connection. The base pin allows the designer to tailor the switching threshold or add a resistor to improve turn-off time beyond the typical 350ns — a useful degree of freedom not available on Darlington or simple phototransistor optos.

Typical turn-on of 220ns and turn-off of 350ns place this part in the fast-switching class for a phototransistor optocoupler. If you are replacing a slower opto in an existing design, check that the minimum CTR of 15% at 16mA forward current still meets your logic-level threshold at the output load — the CTR is specified at 16mA If, so plan the LED drive resistor accordingly. The output transistor is rated for 35V Vce and 8mA continuous output current.

Housed in an 8-SMD Gull Wing package, the PS8501L3--AX is a surface-mount part. ROHS3 compliant per the listing, so no exemption issues for EU or similar regulated markets.

Renesas lists this part as Active.

Frequently asked questions

What is an equivalent substitute for PS8501L3--AX?

The PS2801C-4-V-A is a different part — it is a 4-channel optocoupler with 2500Vrms isolation and slower switching (10µs/7µs). It is not a pin-compatible or functional substitute for the single-channel 5000Vrms PS8501L3--AX. Stick with the exact order code unless you are redesigning the isolation barrier and channel count.

Is PS8501L3--AX RoHS compliant?

Yes, it is ROHS3 compliant per the manufacturer's listing.
