General The TOSHIBA TLP3431 is a very small outline non-leaded photorelay suitable for surface-mount assembly. The TLP3431 consists of an infrared LED optically coupled to a photo-MOSFET and is housed in a VSON 4-pin package. The TLP3431 features extremely low On-state resistance, enabling it to be used for high-frequency measuring instrument applications. 3.
