• Photocoupler and Photorelay | Toshiba

TTI, Inc. and Toshiba Announce New Franchise Agreement - Read about it here.
As a type of isolator favored by manufacturers, photocouplers now serve as noise protectors in many electronic devices. Toshiba's photocouplers incorporated into a white mold package, a combination of either GaAs infrared LEDs or GaAIAs infrared LEDs and silicon photodectors, which provides for excellent isolation. GaAIAs LEDs are adopted in photo-IC types for their high speed and high light output. Toshiba's innovative white mold packaging also greatly contributes to high sensitivity, high CTR, and superb reliability.

Toshiba has six types of opto-isolators based on their outputs categorized below:

• IC Coupler - high speed, IGBT/MOSFET and IPM driver coupler
• Photorelay/PhotoMOS - MOSFET output coupler
• Triac Coupler
• Transistor Coupler
• Darlington Transistor Coupler
• Thyristor Coupler
• PDA Coupler - Photodiode array output coupler
