SSRs handle more current

The PS710 series of solid-state relays from NEC Electronics are suitable for replacing electromechanical relays in a wide range of applications.

The PS710 series of solid-state relays from NEC Electronics are suitable for various applications where mechanical relays are going to be replaced by electronic relays as a result of the increase of maximum permissible currents.

In addition to telecommunication solutions, applications include factory automation, measurement equipment and heating systems.

NEC's new PS710-family is suitable for currents up to 2.5A AC and 5A DC.

This new family of OC-mosfets (optically coupled) are all housed in 6-pin DIL packages.

The isolation voltage between input and output is 1500V RMS.

Typical input operating current (LED current) is 10mA.

The typical turn-on time is below 5ms.

The PS710 family features low on-resistance, which can be as low as 0.1ohm maximum (PS710B-1A).

The OC-mosfets are highly reliable (no mechanically moving parts) and have a long lifetime.

Initially the PS710-series consists of several types.

The PS710A-1A has a maximum 60V collector-emitter voltage and a maximum 1.8A AC (3.6A DC) continuous load current.

The PS710B-1A also has a maximum 60V collector-emitter voltage, with a maximum 2.5A AC (5.0A DC) continuous load current.

The PS710CL2-1A offers a maximum 60V collector-emitter voltage, with a maximum 2.0A AC continuous load current and the PS710E-1A provides maximum 80V collector-emitter voltage with a maximum 2.0A AC (4.0A DC) continuous load current.

For surface mount - lead bending version of above relays - the ordering part number is PS710xL-1A.

Each solid-state relay is available in two versions.

The PS710x-1 series is adapted for soldering with lead and the PS710x-1-A series is the ideal choice for lead-free soldering.

Samples are available on request from Sunrise Electronics.
