Toshiba Utilizes AlGaAs LEDs Technology in IC Photocouplers

Toshiba America Electronic Components (TAEC)  has introduced  its new  family of photocouplers, the TLP700A and TLP705A.

They are housed in small packages (SDIP6),  half the size of conventional 8 pin DIP packages, and consist of an AlGaAs infrared LED, optically coupled to an integrated high-gain, high-speed photodetector IC chip.

About  TLP700A
Its TLP700A can directly drive a middle-capacity IGBT or power its MOSFETs.

With a guaranteed transmission delay skew, ideal for designing dead time for inverters, this product achieves a shorter transmission delay time,  roughly half of the firm's previous model.

With improved peak output current and operating ambient temperature, the TLP700A is suitable for use in high temperature environments. The device also complies with the reinforced insulation class of international safety standards.

The TLP700A can be used in a wide range of products, including industrial devices, digital home appliances, measurement devices, and control devices. Its small packaging can contribute to a smaller footprint and cost reduction.

About  TLP705A
The TLP705A can directly drive a small-capacity IGBT and power MOSFETs.

Using a new LED with excellent longevity, the TLP705A has better output current, variation in transmission delay time, and transmission delay skew characteristics than those of the existing model.

Toshiba's new IC complies with the reinforced insulation class of the international safety standards, and can be used in a wide range of products - including industrial devices, digital home appliances, measurement and control devices.

Joseph Tso, business development manager for Toshiba's optoelectronics discrete business unit,said that , "Toshiba's new photocouplers provide a smaller footprint solution for applications that require safety standard certifications, while also contributing to cost reductions."
