Photorelays are a type of photocouplers consisting of an LED on the input side and a MOSFET on the output side. 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.
Advantage of Photorelay
We will be introducing the merits of replacing mechanical relays with photorelays, and the unique features of Toshiba Photorelay such as ultra-small packages and large current type photorelays.
