• Photocouplers | Toshiba

Toshiba has a complete line-up of optical semiconductor applied products including mini-flat phototransistor couplers with reinforced isolation in component TLP285. A new phototransistor coupler in the SOP4 mini-flat package, the TLP285 provides reinforced isolation compliant with international safety standards.  The compact package is ideal for size reduction and space saving design requirements, resulting in a smaller and thinner end product.

The high isolation voltage (3750 Vrms AC minimum) and the wide operating temperature range (Ta = -55 °C to 110 °C) make the TLP285 suitable for a variety of applications such as power supplies and hybrid ICs requiring high-density board assembly; home appliances; communications equipment; various controllers and so on.
