Photorelays (MOSFET Output)

Photorelays are a type of photocouplers consisting of an LED optically coupled with a MOSFET. Photorelays offer many advantages over mechanical relays such as long service life, low-current drive and fast response. Photorelays are widely used for contact switching in semiconductor test systems, security systems, etc. Toshiba offers low RON, low COFF photorelays in ultra-small VSON/S-VSON packages for semiconductor test system applications, and general-purpose photorelays in various packages featuring high current and high off-state voltage.

Contact (Mechanical Relay) and Contactless (Semiconductor Relay)
What is a photorelay?
Relays are electrically operated switches and can be broadly classified into contact (mechanical) and contactless (semiconductor) types. Photorelays are semiconductor relays consisting of an LED optically coupled to a MOSFET and are used mainly as signal relay replacements. Having no movable contacts, photorelays are known to have better long-term reliability than mechanical relays.

Evaluation Board

Discover the benefits of replacing a mechanical relay with a Toshiba photorelay. This photorelay evaluation board replaces a mechanical relay by attaching directly to the mechanical relay mounting board.
