Technical Details & Description

What this optoisolator does and where it fits

The HCPL0611 is a single-channel optoisolator from onsemi with an open collector output, rated for 10 Mbps data rate and 3750 Vrms isolation. It accepts a DC input and operates from a 4.5V to 5.5V supply, making it a direct fit for 5V logic-level isolation in industrial communication buses, PLC interfaces, and motor-drive feedback paths.

Key parametric limits that affect your BOM

Common-mode transient immunity is specified at a minimum 15 kV/µs, which means the output does not glitch when a fast voltage step (like a motor-drive PWM edge) couples across the isolation barrier. This is the spec that separates a reliable industrial link from one that drops bits under surge.

No stock-holding claim; every order is sourced per RFQ.

Frequently asked questions

How can I order HCPL0611 or request a quote?

Submit an RFQ with your target quantity and delivery timeline. The part is Active and ROHS3 compliant; we source it through authorized distribution and provide a competitive quote against your BOM line. Pricing and lead time are confirmed at quote time.

Is HCPL0611 compatible with 3.3V logic?

The supply voltage range is 4.5V to 5.5V, so the input side expects a 5V nominal rail. The open collector output can interface with 3.3V logic if the pull-up resistor is tied to 3.3V, but the input threshold and LED forward current are designed for 5V operation. For 3.3V input compatibility, consider the HCPL0631 or similar parts with lower input threshold.

What is the closest pin-compatible alternative to HCPL0611?

Within the same onsemi family, the HCPL0601 offers a lower data rate (10 Mbps vs 10 Mbps — same speed) but with a different output topology. The HCPL0631 is a direct speed match with a higher common-mode transient immunity. Both share the same 8-SOIC footprint and pinout. Verify the output type and isolation rating against your application before substituting.
