As a type of isolator favored by manufacturers, photocouplers
now serve as noise protectors in many electronic devices.
Toshiba’s photocouplers consist of either a GaAs or GaA As
infrared LED(s) and a silicon photodetector(s) housed in a mold
package. GaA As LEDs are adopted in high-speed photo-IC
types due to their high-speed and high-light output.

To meet customers’ various needs, we offer an extensive
product portfolio shown below as well as general-
purpose photocouplers.
UL approval has been obtained under file number E67349 for
most of our photocouplers. EN60747-5-2-approved
photocouplers are also offered with a wide selection of output
(transistor, thyristor, triac, IC output and photorelay). The
designs of these devices meet other standards including
IEC380/VDE0806, IEC60950/EN60950 and IEC60065/EN60065.
Toshiba offers a wide variety of photocouplers in a small
package to meet the space-saving requirement of increasingly
smaller and thinner end products. Packaging options include
mini-flat packages (MFSOPs) and half-pitch (1.27 mm) mini-flat
SOP packages.
Part of the general-purpose photocouplers with transistor and
triac outputs are manufactured by Toshiba Semiconductor
Thailand Co., Ltd. This will help customers procure components
locally for overseas assembly of end products.
