Product details

Dual-channel isolation in an 8-SOIC footprint

The MOCD213M packs two independent transistor-output optocouplers into a single 8-SOIC package, saving board space compared to two single-channel parts. Each channel provides 2500Vrms galvanic isolation between a DC input LED and a phototransistor output, rated for continuous operation from -40°C to 100°C.

Switching speed and output drive for PLC and sensor interfaces

Typical turn-on time of 3µs and turn-off time of 2.8µs, with rise/fall times of 1.6µs and 2.2µs respectively — fast enough for 24V PLC digital inputs, encoder pulse trains, and sensor status signals up to a few hundred kHz. Each output can handle up to 70V and 150mA continuous, with a maximum Vce saturation of 400mV at rated current. That gives enough headroom to switch 5V or 24V logic rails directly, or drive a small DC load without a buffer transistor.

It is ROHS3 compliant and supplied in tubes.

Sourcing and package availability

Available in the 8-SOIC surface-mount package (0.154-inch body width, 3.90mm width). The dual-channel layout means the same PCB footprint as a standard SOIC-8, but with two isolated channels instead of one.

Frequently asked questions

What is the difference between the MOCD213M and the MOCD213?

The 'M' suffix typically denotes the surface-mount 8-SOIC package variant. The MOCD213 (without M) is often the DIP-8 through-hole version. Both share the same dual-channel transistor-output core and 2500Vrms isolation rating, but the package differs — the MOCD213M is for surface-mount assembly, the MOCD213 for through-hole. Confirm the package in your BOM before substituting.

Can the MOCD213M be used for 5V logic isolation?

Yes — the output transistor can handle up to 70V and the minimum CTR of 100% at 10mA input means the output can pull a 5V logic input low with margin. The 3µs typical turn-on time is fast enough for most logic-level signals below 100 kHz. Just ensure the forward current through the LED stays below 60mA absolute maximum.
