Digital Input Module

The TVS diode (ESD protection diode) is used to protect the internal circuit from noise and surges that enter from the outside. For signal communication in the module circuit, the external signal line must be isolated from the body. Optical-coupled photocouplers provide simple and reliable isolation. A transistor output photocoupler or an IC output photocoupler which has high-speed communication capability is recommended. In addition, it is essential to observe the safety standards established in each country. Toshiba Photocouplers have been approved by UL1577, VDE:EN60747-5-5, EN62368-1, and other organizations.

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

Preventing damage or malfunction of the device due to external surge voltage, wide line-up of protection diodes ranging from one line to four lines is available in a small package, and high ESD tolerance and circuit protection performance realized by original process technology.

Toshiba's portfolio of isolators/solid state relays includes photocouplers, solid-state relays and fiber-optic transmission modules. Toshiba's photocouplers help improve the safety, cut the power consumption and reduce the size of end products.

Toshiba was first in the world to release one-gate logic ICs. As a pioneer in the industry, we will expand the lineup of various products, such as small, thin and low-voltage-operation products.
