Circuit Description

Example of Interface Circuit Block Diagram

In Europe and North America, where the central heating and cooling system is the mainstream, systems for heating, cooling and ventilation are developing, and thermostats are constantly connected to these systems. This system is connected to a motor or the like, and the thermostat is always exposed to motor noise or abnormality. Isolation from the system is essential to avoid this risk. Photorelays are preferred for such isolation.

Toshiba's photorelays have a wide range of on-state current (ION) and low on-state resistance (RON). Small packages are also available that are designed to be compact and have design flexibility.

Examples of typical recommended products are listed below, and also provide a link to the online distributor inventory search page to buy the product.

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.
