Product details

Single-channel 2500Vrms optoisolator in 8-SOIC

The MOC211VM from onsemi is a single-channel optoisolator with a DC input and a transistor-with-base output, rated for 2500Vrms isolation.

Parametric fit for signal isolation

The transistor output with base access gives you flexibility: you can bias the base for faster switching or use it in a common-emitter configuration. Minimum CTR is 20% at 10 mA forward current, which means at 10 mA LED drive you get at least 2 mA collector current — enough to drive a logic input or a small relay. The 150 mA continuous output current and 30 V output rating cover most low-side switching and level-shifting tasks.

That means you can place the MOC211VM on your BOM without a short-term obsolescence watch.

Frequently asked questions

What package does the MOC211VM come in?

8-SOIC with 0.154-inch body width, surface-mount. The supplier device package is also 8-SOIC. Bulk packaging means loose tubes — no tape-and-reel, so order accordingly for pick-and-place or hand assembly.

Can the MOC211VM replace the MOC211?

The MOC211VM is a surface-mount variant (8-SOIC) of the through-hole MOC211. The electrical specs — 2500Vrms isolation, 20% min CTR, 150 mA output — are the same core ratings. If your board layout is for the SOIC footprint, the MOC211VM is the direct drop-in. For a through-hole board, you would need an adapter or the through-hole version.
