Toshiba Strengthens Lineup of Optocoupler Offerings With New Family Of Quad Configuration Couplers

October 19, 2011

Half-Pitch 4-ch Transistor Photocouplers Offer Wider Creepage Distance and Higher Operating Temperatures

IRVINE Calif., — Toshiba America Electronic Components, Inc., (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, has announced the addition of the TLP290-4 (AC input) and TLP291-4 (DC input) to its family of optocouplers. Suitable for general purpose applications requiring isolation, including power supplies and motor controllers, the new optocouplers from Toshiba feature a quad configuration in a double - molded package and a wider creepage distance, improved performance and higher operating temperatures (110 degrees Celsius).

The Toshiba TLP290-4 and TLP291-4 both consist of a photo transistor that has been optically coupled to a gallium arsenide infrared emitting diode. The devices are housed in a low profile SO16 package, making for extremely small and thin couplers. TheTLP290-4 and TLP291-4 feature a wide operating temperature (Ta=-55 to 110 degrees Celsius), making them suitable for high-density surface mounting applications such as programmable controllers and hybrid ICs.

According to Joseph Tso, business development manager for Toshiba's optoelectronics discrete business unit , "This new family of quad couplers can be used in the same socket as our popular TLP280-4 and TLP281-4 series of optocouplers, offering higher performance and greater creepage distance for designs in which package height is of a lesser concern."

Features of the TLP290-4 and TLP291-4 include:

  • Four channels
  • AC Input and DC Input
  • High Operating Temp (110 degrees Celsius)
  • Creepage distance: 5 mm (min)
  • Safety Standard: EN60747-5-2 approved
  • Isolation voltage: 2500 Vrms
  • Max operating insulation voltage: 565 Vpk(max)


The Toshiba TLP290-4 and TLP291-4 are available now. The TLP290-4 is priced at $0.90 each in low quantities and the TLP291-4 is priced at $0.72 in low quantities.
