Photocouplers Photorelay TLP3351 TLP3351 1. Applications High-Speed Memory Testers High-Speed Logic IC Testers Radio-Frequency Measuring Instruments ATE (Automatic Test Equipment) 2. General The TLP3351 is a photorelay in a 4-pin USOP that consists of a photo MOSFET optically coupled with an infrared LED. The TLP3351 features low output capacitance, COFF, and thus fast on/off switching of a high-frequency signal, making it ideal for switching applications in high-speed testers. 3.
