Phototransistors optically coupled to two InGaAs infrared emitting diodes

Available now from Mouser, Toshiba's TLP292-4 InGaAs infrared and phototransistor photocoupler consists of phototransistors optically coupled to two InGaAs infrared emitting diodes connected inverse parallel. The devices can operate directly with AC input current. The TLP292-4 is housed in a very small and thin SO-16 package. Each TLP292-4 has a guaranteed wide operating temperature (Ta=-55C to 12C) and high isolation voltage (3750Vrms). This makes it suitable for high-density surface-mounting applications such as switching power supplies, programmable controllers and simplex / multiplex data transmissions.
