The TLP3412SRHB from Toshiba is a Photorelay that is suitable for ATE (Automatic Test Equipment), probe cards, measuring instruments, high-speed logic IC testers and high-speed memory tester applications. It requires an operating voltage of up to 3.9 V and can handle an on-state current of up to 400 mA. This normally-open photorelay has an on-state resistance of less than 1.5 ohms and an isolation voltage of 500 Vrms. It operates over a wide range of temperatures from -40°C to 135°C and has an off-state output terminal voltage of 60 V. This very small outline non-leaded photorelay has a built-in input resistor, which eliminates an external input resistor for space saving. It features low off-state current and low output pin capacitance. This photorelay is available in a surface-mount package that measures 2.00 x 1.45 x 1.30 mm.
