Toshiba Strengthens Lineup of Optocoupler Offerings with New Family of Quad Configuration Couplers

Toshiba America Electronic Components, Inc. (TAEC) 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°C).

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. The TLP290-4 and TLP291-4 feature a wide operating temperature (Ta=-55 to 110°C), 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°C; creepage distance: 5 mm (min); safety standard: EN60747-5-2 approved; isolation voltage: 2500V(rms); 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.
