The TLP3414S from Toshiba is a Photo Relay that has been designed for surface-mount assembly operations. It requires an input voltage of up to 32 V. This photo-relay consists of an infrared-emitting diode that is optically coupled with a photo-MOSFET. It offers a very low on-state resistance of less than 3 ohms, thereby making it suitable for use in high-frequency measuring instruments. The LED diodes can be triggered by providing an input forward current of up to 3 mA. This photo-relay provides an isolation voltage of more than 500 V (RMS). It is available in a compact surface-mount package that measures 2 x 1.45 x 1.3 mm and is ideal for automated test equipment (ATE), high-speed IC testers, high-speed memory testers, and measurement applications.
