Quad Configuration Optocoupler
Toshiba America Electronic Components, Inc., 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.
