Transistor Output Photocouplers
Transistor-output photocouplers are used for a wide range of applications such as feedback circuits in power supplies and interfaces in industrial equipment.
Photovoltaic Output Photocouplers (for MOSFET Drive)
In a photovoltaic-output photocoupler, the light emitted by an LED is received by a photodiode array (PDA), which converts it into an output voltage.

Digital Isolators

Standard Digital Isolators
Toshiba Standard Digital Isolator features excellent noise resistance characteristics and high-speed signal transmission. It adopts a wide range of applications, from consumers to industrials where severe design is required.

Solid State Relays

Photorelays (MOSFET Output)
Photorelays are semiconductor relays consisting of an LED optically coupled to a MOSFET that are used mainly as replacements for signal relays. Having no movable contacts, photorelays are known to have better long-term reliability than mechanical relays.
Automotive Photorelays (MOSFET Output)
Automotive photorelay supports IATF16949. Non-contact relays contribute to power saving and long life. The combination of photovoltaic coupler and MOSFET can be used to realize contactless relay.
Triac Output Photocouplers / Thyristor Output Photocouplers
Triac-output photocouplers are suitable for controlling AC loads. Thyristor-output photocouplers are used to control AC loads that are directly connected to a 100-Vac or 200-Vac commercial power supplies or to protect power supplies etc.
Photovoltaic Output Photocouplers (for MOSFET Drive)
In a photovoltaic-output photocoupler, the light emitted by an LED is received by a photodiode array (PDA), which converts it into an output voltage.

Fiber Optic Transmitting Modules

Fiber Couplers (TOSLINK™)
A fiber coupler (TOSLINK™) is an optical transmission device that converts a digital electric signal into an optical signal to transmit data.
